在Chrome上使用Jquery检测shift +点击 [英] Detecting a shift + click with Jquery on Chrome

问题描述

我尝试使用javascript检测转换点击，但由于某种原因，它仅适用于IE

I'm trying to detect a shift click with javascript but for some reason it only works on IE

.click(function (e) {
    if (e.shiftKey) {
        Rain();
    }
});

这是我在IE中使用的代码，我如何在Chrome上检测它

this is the code that work for me in IE, how can I detect it on Chrome

推荐答案

我不认为有一个定义的组合，但你可以自己做。一个（粗略的）例子：

I don't think there is a defined combo, but you could make it yourself. A (crude) example:

<div id="someElement">
    Click me for an alert!
</div>

<script>
var shiftPressed = false;
$(document).keydown(function(event) {
    shiftPressed = event.keyCode==16;
});
$(document).keyup(function(event) {
    if( event.keyCode==16 ){ shiftPressed = false; }
});

$('#someElement').on('click', function(e){
    if( shiftPressed ){
        alert("Shift and click!");
    }
    else{ alert("Nope"); }

});
</script>

只需绑定 .keyup（） 当keydown是为了最大限度地减少事件数量的转变。你应该在if语句之外添加尽可能少的逻辑，因为这个事件被触发很多

You could improve it by only binding the .keyup() when the keydown is a shift in order to minimize the number of events. You should add as little logic as possible outside the if statements, as this event gets fired a lot
