由 ≡放荡痞女 提交于 2021-02-15 07:19:34
问题 I am presenting an image embedded in a descriptive text item, followed by several questions about that image. I would like that item to remain in place while the participant scrolls. I've been able to get the entire image to remain in place using something like this HTML code: <html> <style> .image{position: fixed; background: white;} </style> <div class = "image"> <img src="LOCATION OF IMAGE FILE" style="width: 395px; height: 395px;" /> </div> </html> But this freezes the image itself in a

Default handler for a functional class in JavaScript

由 坚强是说给别人听的谎言 提交于 2021-01-28 10:58:30
问题 I wanted to know if it is possible to have a functional class have a default call method. Let me elaborate. function Foo(){ /*some logic*/ Foo.prototype.aletUser = function alertUser(message) { alert(message); } } Assume that the code above is my functional class (if my naming for the above structure is wrong please tell me), and i instantiated one of this structure. let param = new Foo(); Now, i wish to call the following and hope for it to call my prototype Foo.alertUser param('Hey There')

How to remotely simulate a dropdown selection

由 让人想犯罪 __ 提交于 2021-01-28 08:12:05
问题 I have several dropdown select menus where a selection of the first changes the options of the second and a selection on the second changes the options of the third, and so on. I would like to remotely simulate a change (i.e. without the user clicking in the select menu) in the dropdown menu which will activate the Javascript to set the next dropdown's options. Just setting the value of the select menu - document.getElementById('...').value='....' - does not stimulate the Javascript events on

Object.values() in jQuery

由 為{幸葍}努か 提交于 2020-06-24 12:24:50
问题 The prototypeJS library has a method Object.values() which returns an array of values in an object. EG: var myObj = { "key1" : "val1" "key2" : "val2" } Object.values(myObj) //returns ["val1", "val2"] is there a jQuery method that does the same thing? 回答1: Using ES6, you can do the following: Object.values = x => Object.keys(x).reduce((y, z) => y.push(x[z]) && y, []); This simply returns an array containing the object's values. No need for JQuery, _ or anything else. note: Object.values() is

Detect double Ctrl keypress in JS

由 青春壹個敷衍的年華 提交于 2020-05-13 05:03:51
问题 I have a custom CMS and would like to add a "shortcuts menu" triggered by the pressing of the Ctrl key twice within, say, 300 milliseconds. I use prototype, so my starting point obviously is: Event.observe(document, 'keypress', function(event) { if(event.keyCode == Event.KEY_XYZ) { show_shortcuts}); My approach at the moment would be populating a global variable with the current time in milliseconds, and checking on each keypress whether a keypress has happened less than 300 milliseconds ago.

问题 I'm at a loss. I found a few things that mentioned IE needed to have the response type specified and I changed that to text/html and that did nothing for me.
