onload

问题 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. 回答1: You need to hook on to AssemblyLoad event. Refer- http://msdn.microsoft.com/en

问题 In Angular, I'm converting blob to base64 FileReader. But I want to remove the data:application/octet-stream;base64, at the start. getRecordedAudio() { if (this.recordedAudio) { let fileReader = new FileReader(); fileReader.onloadend = function() { let base64data = fileReader.result; //base64data = base64data.split(',')[1]; ---> How can this be done? console.log('base64data-', base64data); }; fileReader.readAsDataURL(this.recordedAudio); } } How can I do this? I'm getting error: Property

问题 I have this loop code to reduce the DOM calls in my javascript, and reuse them. aarr = []; for (var z=1; z<=10; z++) { c = z-1; aarr[c] = document.getElementById("a"+z); } I have been shown that if the code is ran before the DOM is complete, then the array is null. Moving the script after the last html code will work. So now I want to put this code inside the window.onload event so to not have to move the script code to the bottom of the page. But it apparently does not work because it

问题 I had my code something like this: window.onload = function() { var x = document.createElement("INPUT"); x.setAttribute("type", "text"); x.setAttribute("value", ""); document.body.appendChild(x); } And I wanted to write something more, I added a new line. Like this: window.onload = function() { var x = document.createElement("INPUT"); x.setAttribute("type", "text"); x.setAttribute("value", ""); document.body.appendChild(x); document.write("<br>"); } And then, suddenly, my input tag

问题 I use a JavaFX webview in my application. With the following code I set a member after the page has been loaded webEngine.getLoadWorker().stateProperty().addListener(new ChangeListener<Worker.State>() { @Override public void changed(ObservableValue ov, Worker.State oldState, Worker.State newState) { if (newState == Worker.State.SUCCEEDED) { JSObject window = (JSObject) webEngine.executeScript("window"); window.setMember("mymember", new JavaScriptBridge(this)); } } }); Now in javascript I can

问题 I'm creating my portfolio website. I'm looking to add class on document ready, and remove/change that class to a different class on hover. I'm using lightgallery & CSS gram filters to my images on load and hover. $(document).ready(function() { $("#gallery li a").load(function(){ $($(this).find("img")[0]).addClass("inkwell"); }); $("#gallery li a").hover(function(){ $($(this).find("img")[0]).removeClass("inkwell").addClass("mayfair"); }); }); the jQuery code above didn't seem to work well.

问题 Populating a jQuery UI Dialog with a longish table, I would like to have it scroll to the last row in the table having a specific class. I found two other posts almost identical to this here, and here, but I can't get it to work. I've mocked it up at jsFiddle in the hope that someone might help me see the error in my thinking on it. Here is the basic code jQuery(document).ready(function() { var content = jQuery('#amtz_div').html(); var title = 'Amortization Schedule'; var open = function() {

问题 I was using something like this: $(document).ready(function() { $('#my-img').load(function() { // do something }); }); But sometimes it fails to execute the second callback (without throwing any errors, so there's nothing to do there), and I'm thinking that maybe the image is being loaded before the document is ready. If I don't use the $(document).ready() part, it works fine, so I think I'm gonna leave it that way for now. But someone told me that it was a good practice to always do this

问题 I'm using the canvas feature of html5. I've got some images to draw on the canvas and I need to check that they have all loaded before I can use them. I have declared them inside an array, I need a way of checking if they have all loaded at the same time but I am not sure how to do this. Here is my code: var color = new Array(); color[0] = new Image(); color[0].src = "green.png"; color[1] = new Image(); color[1].src = "blue.png"; Currently to check if the images have loaded, I would have to
