[英]jquery event.target is_a_child_of(element)
Given element
, a variable containing a javascript object/DOM element, how do I determine if the event.target is an element inside element
or not? 给定
element
,一个包含javascript对象/ DOM元素的变量,如何确定event.target是否是元素内部的element
?
function(event){
// assume that var element exists in this scope
if(event.target == a_child_of(element))
// do something
}
<div id="myDiv">
<div class="innerDiv">
<input type="text"/>
</div>
</div>
If element
is myDiv
, an event occurring on the inner div or the input, or any other element that may exist inside myDiv
should cause the statement to evaluate to true. 如果
element
是myDiv
,则内部div或输入上发生的事件或myDiv
中可能存在的任何其他元素应导致该语句计算为true。
I imagine that I could use a recursive function to build an array of child elements and then check if the event.target is in the array, but I want to see if there's a simpler answer first. 我想我可以使用递归函数来构建子元素数组,然后检查event.target是否在数组中,但我想先看看是否有更简单的答案。
jQuery救援 :
if (jQuery.contains(element, e.target))
