onkeyup

问题 I'm using the rottentomatoes movie API in conjunction with twitter's typeahead plugin using bootstrap 2.0. I've been able to integerate the API but the issue I'm having is that after every keyup event the API gets called. This is all fine and dandy but I would rather make the call after a small pause allowing the user to type in several characters first. Here is my current code that calls the API after a keyup event: var autocomplete = $('#searchinput').typeahead() .on('keyup', function(ev){

问题 The following works great when the enter key is released. What other options are available for the keyup in addition to keyup.enter ? <input #inputstring (keyup.enter)="doSomething(inputstring.value)"/> 回答1: These are the options currently documented in the tests: ctrl, shift, enter and escape. These are some valid examples of key bindings: keydown.control.shift.enter keydown.control.esc You can track this here while no official docs exist, but they should be out soon. 回答2: I was searching

问题 Hi how can i register and call a server side event for onkeyup event in asp.net textbox. Is it possible? thank you 回答1: TextBox Web control doesn't provide onkeyXXX events instead subscribe to OnTextChanged event; <asp:TextBox ID='Textbox1' runat='server' OnTextChanged='HandleTextbox1OnTextChanged'> </asp:TextBox> public void HandleTextbox1OnTextChanged(Object sender, EventArgs e) { } But you can provide onkeyXXX behavior from client-side. You can add client-side handler like : Textbox1

问题 I have the following setup: Bluetooth scanner iPad Webpage with a textfield for scan input Usage: User focus textfield and scan barcode with bluetooth scanner Scanner adds ENTER (13) at the end of the scan Problem: On Safari in IOS7 there seems to be a change on how keyboard events are handled on bluetooth devices. The code ... window.onkeyup = function (e) { console.log(e.KeyboardEvent) } ... should return information about the key pressed. Instead i get ... keyCode: 0 keyIdentifier:

问题 I'm new to Android development and I can't seem to find a good guide on how to use an onKeyUp listener. In my app, I have a big EditText , when someone presses and releases a key in that EditText I want to call a function that will perform regular expressions in that EditText . I don't know how I'd use the onKeyUp. Could someone please show me how? 回答1: The very right way is to use TextWatcher class. EditText tv_filter = (EditText) findViewById(R.id.filter); TextWatcher

问题 This is a bit of a weird one so I figure I'm either missing something obvious or this is a flaw with how these events are implemented in browsers. Let me first summarize an example scenario this issue comes up with before providing an isolated case-example; The arrow keys are used to move the player (as a handleKeyDown function is fired anytime a key is hit anywhere on the page). Likewise, anytime a key is released another function is fired (handleKeyUp). As you (the player) hold the left key

问题 I'm building a Sql query builder and would like to change the text color of a word in a textarea when the user types in words like SELECT, FROM, WHERE. I've searched around a bit and beyond this (https://jsfiddle.net/qcykvr8j/2/) I unfortunately do not come any further. Example code HTML: <textarea name="query_field_one" id="query_field_one" onkeyup="checkName(this)"></textarea> JS: function checkName(el) { if (el.value == "SELECT" || el.value == "FROM" || el.value == "WHERE" || el.value ==

问题 I'm using MVC 5, C# and I'm trying to build a search filter that will filter through upon each key stroke. It works as so, but the textbox erases after submitting. Now this is probably not the best approach to it either. Is there a way to make so when it posts it doesn't erase the textbox, or better yet, is there a better alternative? @using (Html.BeginForm("Index", "Directory", FormMethod.Post, new { id = "form" })) { <p> Search Employee: <input type="text" name="userName" onkeyup=

问题 I recently added some predictive text input fields to the web-app I am supporting. Big deal, right? Not really, seems like if your web-app doesn't do this -- you are already behind the times and your end-users are complaining. (At least that's how it is over here). So, my question has to do with the "up" arrow key. The predictive textbox has a onkeyup listener. The handler segregates the key strokes and does something depending on the character the user entered. The up arrow key allows the
