  1. Hello & Thanks; Here is a ' mini-Tutorial: moving text to & from <textarea> & <pre> ' http://vmars.us/ShowMe/Tutorial-Textarea-Save-CopyTo-RestoreFrom-onLoad-Restore-RO-VM.html I'll also put code here for safekeeping : <!DOCTYPE html> <html> <head> <!-- https://www.freeformatter.com/html-validator.html http://vmars.us/ShowMe/Tutorial-Textarea-Save-CopyTo-RestoreFrom-onLoad-Restore-RO-VM.html --> <title id="titleId"></title> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta charset="UTF-8"> <style> </style> </head> <body onload="documentURL() , onloadRestoreTextarea()" > <br> <button onclick="saveAs(filename, allHtml)">Save This Page</button> <br><br> <div id="inlineDiv" style="display: inline-block;"> <div style="border-style: solid; align-text: center; border-width: 1px; display: inline-block;"> <button onclick="sendToConcoleLog ()">sendToConcoleLog</button> <br><br> <textarea id="toConsoleLogId" rows="4" cols="12">:</textarea> </div> <div style="border-style: solid; align-text: center; border-width: 1px; display: inline-block;"> <button onclick="saveItAll()">Copy this into PRE</button> <br> <textarea class="copyFrom" rows="4" cols="12"></textarea> </div> <div style="border-style: solid; align-text: center; border-width: 1px; display: inline-block;"> <button onclick="restoreItAll()">Restore this from Pre</button> <br> <pre contenteditable="true" class="pasteInto" ></pre> </div> </div> <!-- id="inlineBlock"> --> <div style="border-style: dotted; align-text: center; border-width: 1px;"> <pre> Thought I would make a turorial so I remember what I learned from you all , and to pass on your wisdom. Hope this helps someone :) Try this: ------------------------------------------------------------------------------------------------------------------------ 1) Type something into "Copy this into Pre" textarea box . Then click "Copy this into Pre" Button . Text is copied into "Restore this from Pre" "pre area ' . And "Copy this into Pre" textarea box , is Cleared . Study This : function saveItAll() ------------------------------------------------------------------------------------------------------------------------ 2) The click on "Restore this from Pre" Button , Text is copied from "Restore this from Pre" area into "Copy this into Pre" area . And "Restore this from Pre" area , is Cleared . Study This: function restoreItAll() ------------------------------------------------------------------------------------------------------------------------ 3) Now Type something into "Copy this into Pre" textarea box Again . Then click "Copy this into Pre" Button . Text is copied into "Restore this from Pre" pre area . And "Copy this into Pre" textarea box , is Cleared . But this time , click the "Save This Page" Button . Study This: function saveAs(filename, allHtml) This .html page will be saved in your Browser's download area . Since the "Restore this from Pre" pre area , is coded as contenteditable="true" , the downloaded page will save the "pre area" text as innerHTML . A nifty feature of 'contenteditable' is that upon opening the saved-page the content of "pre area" is now " hardCoded " into page . Study This: function onloadRestoreTextarea() ------------------------------------------------------------------------------------------------------------------------ See code : So in the ' body ' tag we have : "onloadRestoreTextarea()" which runs the " function onloadRestoreTextarea() " code , when page is loaded . Which copies text from "pre area" to " textarea" box . Also at ' body onload="documentURL() ' page load time: The function: function documentURL() is run , which copies ' this .html ' file's address into the ' title ' tag . BTW: for example (see code) and note that : IF you want to copy what’s typed in the box use .value . console.log(toConsoleLogId.value); IF you want what was hardcoded into the text box’s HTML , use .innerHTML . console.log(toConsoleLogId.innerHTML); Hope this helps someone.... http://vmars.us/ShowMe/Tutorial-Textarea-Save-CopyTo-RestoreFrom-onLoad-Restore-RO-VM.html </pre> </div> <script> var copyFromVar = "one"; function saveItAll() { var blankVar = ""; var fromList; // = document.getElementsByClassName("copyFrom"); var intoList; // = document.getElementsByClassName("pasteInto"); fromList = document.getElementsByClassName("copyFrom"); intoList = document.getElementsByClassName("pasteInto"); for (var i = 0; i < fromList.length; i++) { copyFromVar = fromList[i].value ; intoList[i].innerHTML = copyFromVar; fromList[i].innerHTML = blankVar; fromList[i].value = blankVar; } }// </script> <script> var copyFromVarTwo = "two"; function restoreItAll() { var blankVar = ""; var fromListTwo; // = document.getElementsByClassName("copyFrom"); var intoListTwo; // = document.getElementsByClassName("pasteInto"); intoListTwo = document.getElementsByClassName("copyFrom"); fromListTwo = document.getElementsByClassName("pasteInto"); for (var i = 0; i < fromListTwo.length; i++) { copyFromVarTwo = fromListTwo[i].innerHTML ; intoListTwo[i].value = copyFromVarTwo; copyFromVarTwo = fromListTwo[i].innerHTML ; intoListTwo[i].value = copyFromVarTwo; fromListTwo[i].innerHTML = blankVar; fromListTwo[i].value = blankVar; } } </script> <script> var copyFromVarOnload = "three"; function onloadRestoreTextarea() { var fromListTwo; // = document.getElementsByClassName("copyFrom"); var intoListTwo; // = document.getElementsByClassName("pasteInto"); var blankVar = ""; intoListTwo = document.getElementsByClassName("copyFrom"); fromListTwo = document.getElementsByClassName("pasteInto"); for (var i = 0; i < fromListTwo.length; i++) { copyFromVarTwo = fromListTwo[i].innerHTML ; intoListTwo[i].value = copyFromVarTwo; copyFromVarTwo = fromListTwo[i].innerHTML ; intoListTwo[i].value = copyFromVarTwo; fromListTwo[i].innerHTML = blankVar; fromListTwo[i].value = blankVar; } } // reloadTextarea </script> <script> function sendToConcoleLog() { var var01 = toConsoleLogId.value; console.log(var01); // alert(var01); var var01 = toConsoleLogId.innerHTML; console.log("If nothing after : Then no nothing was typed into this textarea => " + var01); alert("If nothing after : Then no nothing was typed into this textarea => " + var01); console.log(toConsoleLogId.value); console.log(toConsoleLogId.innerHTML); /* should be console.log(toConsoleLogId.value); if you want what’s typed in the box, or console.log(toConsoleLogId.innerHTML); if you want what was hardcoded into the text box’s HTML. */ } </script> <script> var filename = ""; function documentURL() { document_URL = document.URL; document.getElementById("titleId").innerHTML = document_URL; } </script> <script> var filename = "Textarea-Save-CopyTo-RestoreFrom-onLoad-Restore.html"; var allHtml = document.documentElement.outerHTML; function saveAs(filename, allHtml) { allHtml = document.documentElement.outerHTML; var blob = new Blob([allHtml], {type: 'text/csv'}); if(window.navigator.msSaveOrOpenBlob) { window.navigator.msSaveBlob(blob, filename); } else{ var elem = window.document.createElement('a'); elem.href = window.URL.createObjectURL(blob); elem.download = filename; document.body.appendChild(elem); elem.click(); document.body.removeChild(elem); } } </script> </body> </html>
  2. My suggestion is to add HTML DOM element object outerHTML attribute for the JavaScript reference. It seems that most, if not all, the browsers support this attribute. In addition, it is important and basic attribute that new JavaScript developers should know about.
  3. Hi there, I have recently been trying some code out to replace the innerHTML contents from within a table row, i am now to discover that Internet Explorer which a lot of people still use insists of making innerHTML properties read only, although the code works flawlessly in Firefox and Google Chrome. The code i have currently got is shown below: document.getElementsByTagName("tr").innerHTML = document.getElementsByTagName("tr").innerHTML.replace(document.getElementsByTagName("tr").cells[j].childNodes[0].id,nameandid).replace(document.getElementsByTagName("tr").cells[j].childNodes[0].name,nameandid).replace(document.getElementsByTagName("tr").cells[j].childNodes[2].id,calendarid).replace(document.getElementsByTagName("tr").cells[selecttdid].childNodes[0].name,selectname); As you can see from the above code i am trying to tell a tag name TR which has an index of i innerHTML to change to itself but with some things replaced. You don't need to know what i am replacing inside the code as that code is all fine. What i would like to know is, what work around do i have to change the innerHTML using Javascript or JQuery? Some people have said to stick it into a Div tag but the problem is that the table is inside of a form and i am sending the elements from a form to a different page and so i would rather keep it inside the table row. I have also read that innerHTML can be used to modify specific cells from within a table i.e. contents inside a TD tag. Does anybody know how i can modify my code accordingly so that the debugger stops spitting out the "operation" error messages when i put debugging on due to trying to write to innerHTML? I have also tried using outerHTML and didn't seem to work either: document.getElementsByTagName("tr").outerHTML.replace(document.getElementsByTagName("tr").innerHTML,document.getElementsByTagName("tr").innerHTML.replace(document.getElementsByTagName("tr").cells[j].childNodes[0].id,nameandid).replace(document.getElementsByTagName("tr").cells[j].childNodes[0].name,nameandid).replace(document.getElementsByTagName("tr").cells[j].childNodes[2].id,calendarid).replace(document.getElementsByTagName("tr").cells[selecttdid].childNodes[0].name,selectname)); You will notice in the above i am trying to replace the innerHTML of an element(a TR tag at number i) with some things removed and again, because i am trying to modify the innerHTML...it was a no go again. Finally i have tried to modify a value property in internet explorer and this time it spits out a 5007 error saying that it is unable to set the value of the property, anybody know how i can get around this? My code again for this is below to what i currently tried: document.getElementById("unitstartdate"+totaltablerows).value = startdate; The ID's do exist and again this code worked fine in firefox and chrome, just not IE. I think i am more after a work around for both situations rather than you understanding what i am actually trying to replace etc. as the replace part of the code is fine, just will not write to HTML in Internet explorer using innerHTML, outerHTML or change a value of an element as mentioned. Any ideas are great. Mark
