BACKGROUND: I recently install nodejs and npm and downloaded a library call xregexp.js Then, I discovered what I did not know. The applications nodejs (node) and npm are primarily designed for server-side Javascript. Now, I am confused. In PHP one can simply include or require PHP from another document file and employ it wherever you like that PHP can be used. When I try to do something similar with xregexp.js I inevitably fail and am told that the script cannot be found. Now, I have node and npm installed above my domain folders so that it can be used with all of my domains. Simply I do not know how to access the modules that I install with npm, and I was hoping to install several more. QUESTION: How does one access node modules that are installed with npm, but reside above the domain folders in which the Javascript that is targeted to employ them resides? Roddy

Hey there, I have followed the tutorial for the w3 raspberry pi led pwm Gpio controller using node.js (https://www.w3schools.com/nodejs/nodejs_raspberrypi_rgb_led_websocket.asp) unfortunately though it uses internal scripts and stylesheets. I have tried using express.static to set up file hosting but I couldn’t get it to work. I am needing to host additional files for the web server to read. I am fairly new at node.js so it might have been the way I was trying to implement it that caused the issue. Thanks in advance

What About Adding Node.js As Another Tutorial In The Server-Side Languages? to complete the chain of JavaScript and to teach the newer, modern and the attractive part of the language...why not? I am not recommending specific framework W3SCHOOLS can choice any of the available, but please the best! WHY ADDING: I am not here to explain the power of Node.js...Please Google this WHY IT'S NECESSARY: Large companies are using and coming to Node e.g...[Google this also ], and large apps are written with it[Do Not Forget Our friend..Google]. not only it's "Popular", but also fast(because of the non-blocking I/O, being V8 based and more[Google!!!]) THANKS FOR: ADDING NODE AS THE THIRD LANGUAGE

Hi, im a little bit struggling here. What I am trying to do is read the content from a Table by reading the number of rows and cells,(later on only selected rows by checkbox) then display the data in a ´generated Table (where i have to add cells with inputfields) So now my question is: How do i have to write the code so the first row will be created with <th> instead of <td> ? How to add input fields to the cells ? (actually they all could be input fields, just filled out with the data from the table i read from and blank fields for the added or so on.) function generate_table() { // get the reference for the body var body = document.getElementsByTagName("body")[0]; var x = document.getElementById("TableB").rows.length; var y = document.getElementById("TableB").rows[0].childElementCount; var z = document.getElementById("TableB").rows[1].cells[3].innerText; alert("x="+x +" y="+y+" z="+z); // creates a <table> element and a <tbody> element var tbl = document.createElement("table"); var tblBody = document.createElement("tbody"); // creating all cells for (var i = 0; i < x; i++) { // creates a table row var row = document.createElement("tr"); alert("ROW"+row); for (var j = 0; j < y; j++) { // Create a <td> element and a text node, make the text // node the contents of the <td>, and put the <td> at // the end of the table row var cellText = document.createTextNode("cell in row "+i+", column "+j); if (row.tabIndex[0]){ var cell = document.createElement("th"); cell.appendChild(cellText); row.appendChild(cell); } else{ cell = document.createElement("td");} cell.appendChild(cellText); row.appendChild(cell); } // add the row to the end of the table body tblBody.appendChild(row); } // put the <tbody> in the <table> tbl.appendChild(tblBody); // appends <table> into <body> body.appendChild(tbl); // sets the border attribute of tbl to 2; tbl.setAttribute("border", "2"); tbl.setAttribute("class", "tableTest"); }

Hi all,I have this XSLT: <?xml version="1.0" encoding="ISO-8859-1"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:output method="xml" version="1.0" encoding="iso-8859-1" indent="yes"/><xsl:template match="/"><xsl:apply-templates select="//prime"/></xsl:template> <xsl:template match="prime"> <xsl:apply-templates select="note[@style='tt']" /> </xsl:template> <xsl:template match="note/rss/channel"> <xsl:apply-templates select="item"></xsl:template><xsl:template match="item"><item> <title> <xsl:value-of select="title"/> </title> <description> <xsl:value-of select="description"/> </description> <pubDate> <xsl:value-of select="pubDate"/> </pubDate></item></xsl:template><xsl:template match="prime"> <xsl:apply-templates select="note[@style='sms']" /> </xsl:template> <xsl:template match="note/rss/channel"> <xsl:apply-templates select="item"></xsl:template><xsl:template match="item"><item> <title> <xsl:value-of select="title"/> </title> <pubDate> <xsl:value-of select="pubDate"/> </pubDate></item></xsl:template></xsl:stylesheet> I want to show note type =tt and note type = sms in the same page because the content of each type is different, the problem with this xslt is that the note type sms is overwritting the note type = tt, in other words, it's only showing the note type= sms. How can I solve this... Thanks all
