I am having a problem with onLoad event of an iframe on Google Chrome. I created an iframe and set value for its "src" attribute to get a file from server. While server is processing, a waiting box is displayed until client gets the returned file. I tried to use the onLoad event of iframe to detect when client get the file to turn off that waiting box, but on Google Chrome that event handler does not work. With Firefox, when client gets a file, a "Save to" popup will be displayed automatically and event "load" will be fired, but this is not happen on Chrome. Could you please tell me how to

JavaScript - overwriting .onload prototype of HTMLImageElement(s)

由 旧时模样 提交于 2019-11-29 16:05:42
Is it possible to bind an onload event to each image, declaring it once? I tried, but can't manage to get it working... (this error is thrown: Uncaught TypeError: Illegal invocation ) HTMLImageElement.prototype.onload = function() { console.log(this, "loaded"); }; P.S: I also tried returning this , but doesn't seem to be the issue here... any suggestions / explanations on why my current code isn't working? You can't set a handler on the prototype, no. In fact, I'm not aware of any way to get a proactive notification for image load if you haven't hooked load on the specific image element, since

Jquery Chosen focus on page load (onLoad?)

由 本秂侑毒 提交于 2019-11-29 13:26:40
I'm using the Jquery Chosen plugin on a select box, however I'd like to focus this on page load. I've used the following code to focus a text input: onLoad="document.forms.sales_order_form.customer.focus()" But this doesn't work for the select box: <select data-placeholder="Select a Customer..." class="chzn-select" name="customer" style="width:400px;"> <option value=""></option> </select> In Chosen 1.0, this command is now: $('.my_select_box').trigger('chosen:activate'); See here . If your using the first example (standard select box) you can use: jQuery(document).ready(function($) { $('.chzn

Javascript Run Function After Page Load

由 北城以北 提交于 2019-11-29 08:49:47
I'm trying to create a small automation script in Javascript that I want to run with a site using Opera's User Script feature to define external scripts to run. I have used this feature before to run scripts I wrote with external sites, to nice effect. I need to wait till the page loads for the script to run, but I can't seem to get this to work. The code currently is: if (addEventListener in document) { // use W3C standard method document.addEventListener('load', meerfirst(), false); } else { // fall back to traditional method document.onload = meerfirst(); } function meerfirst(){ nameForm =

Hooking into an “OnLoad” for class library

由 最后都变了- 提交于 2019-11-29 08:14:41
Does anyone know if there's a way to hook into an "OnLoad" event to run some operations when an assembly loads? Specifically, I am creating a plug-in for an application. The plug-in's DLL gets loaded and objects start being used, but the problem is I need to load another assembly dynamically before anything happens. This assembly can't be copied to the application's directory and must remain invisible to it. You need to hook on to AssemblyLoad event. Refer- http://msdn.microsoft.com/en-us/library/system.appdomain.assemblyload.aspx It is really sad that writing a Main() function in an Assembly

Javascript onload and onunload

Consider the following HTML snippet containing some javascript utilizing prompt and unload . The prompt() method works fine but I want alerting something like Goodbye, user when reloading or leaving the page. Any help is greatly appreciated. <body onload="promptName()" > <script type="text/javascript"> function promptName() { var userName = prompt("What's your name ?", "") return userName; } function goodBye() { alert("Goodbye, " + promptName() + "!"); } window.onunload = goodBye(); </script> </body> You should write it like this: window.onunload = goodBye; Also, you might consider using the

How to execute JavaScript after page load?

由 有些话、适合烂在心里 提交于 2019-11-29 05:36:12
I would like to execute a JavaScript function after the page was loaded. At the moment I have a commandButton and everything works fine. However it would be more comfortable if the user is not supposed to hit the button. I have tried f:event, but I do not have a listener, I have only the JavaScript function. Moreover body onload does not work for me as I use only high level components. <f:view xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:pm=

window.onload does not work in AngularJS

由 二次信任 提交于 2019-11-29 03:24:38
This code in a simple HTML file works: <script> function load() { alert("load event detected!"); } window.onload = load; </script> However, if I put it into the index.html file of an AngularJS web app, it does not. Does anybody know why not? Call your function with ng-init var app = angular.module('app',[]); app.controller('myController', function($scope){ $scope.load = function () { alert("load event detected!"); } }); <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app='app'> <div ng-controller='myController' ng-init='load()'></div> </div

Basically I want to make this: <li id="about"><a href="#">About</a> Into this when the page loads: <li id="about" class="expand"><a href="#">About</a> I found this thread, but am not so good with javascript and couldn't adapt it: Javascript: Onload if checkbox is checked, change li class This should work: window.onload = function() { document.getElementById('about').className = 'expand'; }; Or if you're using jQuery: $(function() { $('#about').addClass('expand'); }); Swaff I would recommend using jQuery with this function: $(document).ready(function(){ $('#about').addClass('expand'); }); This

How to tell whether the $(window).load()/window.onload event has already fired?

由 余生长醉 提交于 2019-11-29 01:25:41
问题 I have a script that is being inserted dynamically via another script. The code in that script is wrapped inside the $(window).load() event because it requires the images on the page to have all loaded. In some browsers it works fine, but in others it seems not to fire because the page has already finished loading by the time the code is run. Is there any way to check and see whether the page has already finished loading - either via jQuery or JavaScript? (including images) In this situation,
