[ad_1] add this jQuery(document).ready(function() { $(“html”).css({ ‘background-image’: ” }); $(“html”).animate({ background:’url(image.png)’},350); }); That’s only for the first image fade effect. If you want this effect for different images you might want to try this plug-in I’m sure you will get cool output from it. 3 [ad_2] solved Fading a background with jQuery [duplicate]
[ad_1] Let’s clean it up: var j = 0; var t = 0; do { j++; t += j; } while (j < 5); alert(t); If you manually expand this (and I will), this is the equivalent code without loops: var j = 0; var t = 0; j++; // j = 1 t += … Read more
[ad_1] Since JavaScript is a C-style language (syntactically derived from Java), all the known coding styles from those worlds are possible. Choose one yourself. If you’re working on a project with other people, you should agree on some coding conventions. Common and influential ones (from larger projects) are: Node.js style guide Crockford’s code conventions Google … Read more
[ad_1] It should be: [array[j], array[j + 1]] = [array[j + 1], array[j]]; instead of: [array[j], array[j + 1] = array[j + 1], array[j]]; Pay close attention to where the square brackets begin and end. Your current code: assigns one array index to itself creates an array with 3 elements and throws it away immediately … Read more
[ad_1] The value you retrieve from the DOM is already a String, but you’re coercing it to a Number by using + in front of +lastrow. Get rid of that + and ditch the .toString() in item_no.toString().substring(2); For addition, the max number in JavaScript is 9007199254740991. So you’ll have to do some addition on a … Read more
[ad_1] You can use some thing like function bind or do it using handler: $add.click(function(e){ myFunction(i); }); 2 [ad_2] solved Javascript add function call with parameters to button

[ad_1] You have no a inside the element with the class PageNumber. $(“.PageNumber”) or even $(“a.PageNumber”) if you want to specify it a bit more You also are looking for an input next to the $(“.PageNumber”). But its next to the li so use var pagenum = $(this).parent().next(‘.page’).val(); You are also using $(this).attr(pagenum); but not … Read more
[ad_1] I’m using http://threedubmedia.com/ instead of JQuery Ui for the drag/drop functionality. This solution can probably be replicated for JQuery Ui. Solution: $(div).drag(“start”, function( ev, dobj) { return $( this ).clone() .css({ opacity: .75, position: ‘absolute’, zIndex: 9999, top: dobj.offsetY, left: dobj.offsetX }).appendTo( $(‘body’)); }) .drag(function( ev, dobj ){ $( dobj.proxy ).css({ “transform”: “translate(” + … Read more
[ad_1] You can use the map() method along with the ES6 fat arrow function expression to retrieve the values in one line like this: users.map(x => x.mobile); Check the Code Snippet below for a practical example of the ES6 approach above: var users = [{mobile:’88005895##’},{mobile:’78408584##’},{mobile:’88008335##’}]; var mob = users.map(x => x.mobile); console.log(mob); Or if you … Read more
[ad_1] I suggest you edit your question to represent accurately what you are looking for. Based on your comments, if you are looking for the FIRST DIV, use something like this:- x=document.getElementsByTagName(“div”); if (x!= ‘undefined’ && x.length > 0 ) document.write(x[0].id); 2 [ad_2] solved find id of element [closed]
[ad_1] The pictured code (please include actual code in the future, not screenshots of code) returns fact immediately: for ( n = 1; n <= num; n++ ) { return fact * n; } since n starts at 1. What you want is to include fact in the function, and multiply it as the loop … Read more
[ad_1] The in operator makes it possible to see whether an object has a property with a particular name. if (“name” in object) { … } Without in, that would be harder. You can test for null or undefined, but that doesn’t answer the question unambiguously. Note that the token in also appears in the … Read more
[ad_1] If you’re using jQuery then use this: $(‘#sensor’).change(function() { $(‘#sensorText’).val( $(this).find(‘option:selected’).data(‘foo’) ) }) $(‘#sensor’).change(function() { $(‘#sensorText’).val( $(this).find(‘option:selected’).data(‘foo’) ) }) <script src=”https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js”></script> <form id=”example” name=”example”> <select id=”sensor”> <option value=”Jval” data-foo=”Jfoo”>Joption</option> <option value=”Kval” data-foo=”Kfoo”>Koption</option> </select> <br /> <input type=”text” value=”” id=”sensorText” /> </form> 1 [ad_2] solved Populate an input with the contents of a custom option … Read more
