Hi I have created a sample project with user name and password. As shown in attached image, three and four are disabled. When i click on three or four buttons which are disabled, Is it possible to get alert with login and password. <html> <head> <script> function one() {document.getElementById("fir") alert("first button"); } function two() {document.getElementById("sec") alert("second button"); } function three() {document.getElementById("thi") alert("third button"); } function four() {document.getElementById("for") alert("fourth button"); } function login() { var password=["1234", "5678"]; var username=["abcd","defg"]; var uid=document.getElementById("uname").value; var pid=document.getElementById("pass").value; if(password[0] == pid && username[0] == uid){ document.getElementById("fir").disabled = false; document.getElementById("sec").disabled = false; document.getElementById("thi").disabled = false; document.getElementById("for").disabled = false; } else if(password[1] == pid && username[1] == uid) { alert("Success"); document.getElementById("thi").disabled = true; document.getElementById("for").disabled = true; } else { alert ("Enter valid username and password"); document.getElementById("fir").disabled = true; document.getElementById("sec").disabled = true; document.getElementById("thi").disabled = true; document.getElementById("for").disabled = true; } } </script> </head> <body> <label for="uname"><b>Username</b></label> <input type="text" id="uname" placeholder="Enter Username" name="uname" required><br/><br/> <label for="psw" ><b>Password</b></label> <input type="password" placeholder="Enter Password" id="pass" name="psw" required><br/><br/> <button onclick="login()" id="log">Login</button><br/><br/><br/> <button onclick="one()" id="fir">one</button> <button onclick="two()" id="sec">two</button> <button onclick="three()"id="thi">three</button> <button onclick="four()" id="for">four</button> </body> </html>

Hi Just the position of " error_prev=error_case;" is changed and now i corrected the setinterval <script> function error_8() { var x8; var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if(xhttp.readyState == 4) { if(xhttp.status == 0) { } else { x8 = this.responseText; if (x8 == 0 ) { document.getElementById("error_pos8").value = "Under Pressure"; error_case = document.getElementById("error_pos8").value; } } } }; xhttp.open("GET", "error_val8.txt", true); xhttp.send(); } setInterval(error_8(), 1000); var error_case,error_prev; function temp1() { var list = document.getElementById("myList"); if(error_prev!==error_case) { list.removeChild(list.children[4]); var newItem = document.createElement("LI"); var textnode = document.createTextNode(error_case); newItem.appendChild(textnode); list.insertBefore(newItem, list.children[0]); } error_prev=error_case; } setInterval(temp1,1000); </script>

At the end error_prev am updating.. still same issue..nothing appears if(error_prev!==error_case) { list.removeChild(list.children[4]); var newItem = document.createElement("LI"); var textnode = document.createTextNode(error_case); newItem.appendChild(textnode); list.insertBefore(newItem, list.children[0]); } error_prev=error_case;

Hi I changed like below. <script> function error_8() { var x8; var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if(xhttp.readyState == 4) { if(xhttp.status == 0) { } else { x8 = this.responseText; if (x8 == 0 ) { document.getElementById("error_pos8").value = "Under Pressure"; error_case = document.getElementById("error_pos8").value; error_prev=error_case; } } } }; xhttp.open("GET", "error_val8.txt", true); xhttp.send(); } setInterval(error_8(), 1000); var error_case,error_prev; function temp1() { var list = document.getElementById("myList"); if(error_prev!==error_case) { list.removeChild(list.children[4]); var newItem = document.createElement("LI"); var textnode = document.createTextNode(error_case); newItem.appendChild(textnode); list.insertBefore(newItem, list.children[0]); } } setInterval("temp1()",1000); </script> I have similar functions from error_1 to error_8 error_prev=error_case; is present in all 8 functions i tried above but its not working

Hi This works fine. Am receiving the data from server using ajax every 1 sec. I need to avoid if same data is appearing, i mean only when different data appears.i need to delete child[4] and display the new data at child[0] position. so i tried this way.will this work AJAX: if (x8 == 0 ) { document.getElementById("error_pos8").value = "Under Pressure"; error_case = document.getElementById("error_pos8").value; } INSERTBEFORE: if(error_case!=document.createTextNode(error_case)) { newItem.appendChild(textnode); list.insertBefore(newItem, list.children[0]); }

Hi I am trying the simple method by referring w3schools <!DOCTYPE html> <html> <body> <ul id="myList"> <li>Coffee</li> <li>Tea</li> <li>milk</li> <li>complan</li> <li>boost</li> </ul> <button onclick="myFunction()">Try it</button> <script> function myFunction() { var list = document.getElementById("myList"); list.removeChild(list.childNodes[4]); var newItem = document.createElement("LI"); var textnode = document.createTextNode("Water"); newItem.appendChild(textnode); list = document.getElementById("myList"); list.insertBefore(newItem, list.childNodes[0]); } </script> </body> </html> 1.My intention is to remove the last element 2.then add "water " to first line using insert before Need to do it in same function, one should delete and other to add after deleting. But this is not working anything wrong here

Hi Am using below example for insertbefore method <p id="error_pos8"></p> <ul id="alerts_errors_list"> </ul> <script> function error_8() { var x8; var xhttp = new XMLHttpRequest(); xhttp.onreadystatechange = function() { if(xhttp.readyState == 4) { if(xhttp.status == 0) { document.getElementById("error_pos8").innerHTML = this.responseText; } else { x8 = this.responseText; if (x8 == 0 ) { document.getElementById("error_pos8").innerHTML = "Under Pressure"; error_case = document.getElementById("error_pos8").innerHTML; } } } }; xhttp.open("GET", "error_val8.txt", true); xhttp.send(); } setInterval(error_8(), 1000); var error_case; function alerts_errors() { var newItem = document.createElement("LI"); var textnode = document.createTextNode(error_case); newItem.appendChild(textnode); var list = document.getElementById("alerts_errors_list"); list.style.color = "red"; list.insertBefore(newItem, list.childNodes[0]); } setInterval("alerts_errors()",100000); </script> whether the below code works fine for insertbefore ,because i have similar code for 8 other error list x8 = this.responseText; if (x8 == 0 ) { document.getElementById("error_pos8").innerHTML = "Under Pressure"; error_case = document.getElementById("error_pos8").innerHTML; } so now error case should be printed only when it satisfies the x1==0 to x8==0 condition Will it be fine
