使用jQuery触发按键 [英] Trigger Keypress with jQuery

问题描述

在>确定触发器Keypress jQuery线程上，没有有效的JSFiddle来寻找答案，并且那里的代码对我不起作用.

On the Definitive Trigger Keypress jQuery thread there is no working JSFiddle for the answer, and the code that is there doesn't work for me.

$("button").click(function () {
    $("input").focus();
    var e = jQuery.Event("keydown");
    e.which = 77; // # Some key code value
    $("input").trigger(e);
})

有我的代码，这是我的小提琴 http://jsfiddle.net/Z8adb/

There's my code and here's my fiddle http://jsfiddle.net/Z8adb/

单击时，在输入中应出现M，因为输入已获得焦点并具有按下其keyCode为77("m")的keydown.

On click, an M should appear in the input, as the input is given focus and having a keydown with the keyCode of 77 ("m") triggered on it.

有什么想法吗?

我的真正目的是在Sublime Video上触发"m"热键，以便以编程方式使视频静音.这是确保我正确触发"m"键的第一步，而这正是我借助Stack Overflow进行的.但是，我仍然无法在视频上以编程方式触发事件.我认为这只是Sublime Video的问题，但我不确定，任何人对强迫按键和单击的看法都会令人赞叹.

My true purpose for this is to trigger an "m" hotkey on a Sublime Video in order to mute the video programmatically. This was my first step to ensure I was firing the "m" key properly, which I am with the help of Stack Overflow. However, I'm still not able to get an event to fire programmatically on the video. I think this is just a problem with Sublime Video, but I'm not sure, and anyone's views on forcing keypresses and clicks would be awesome to hear.

推荐答案

使用触发器，您只是通过键码触发事件，而没有将值分配给文本框.试试:- http://jsfiddle.net/PbHD2/

Using trigger you are just triggering the event with a keycode but not assigning the value to the textbox. Try this :- http://jsfiddle.net/PbHD2/

String.fromCharCode

$("button").click(function() {
     $("input").focus();
    var e = jQuery.Event("keydown");
    e.which = 77; // # Some key code value
    $("input").val(String.fromCharCode(e.which));
    $("input").trigger(e);
});
$('input').keydown(function(e){
   console.log('Yes keydown triggered. ' + e.which)
});
