e.target（）不适用于表元素

Question

The event.target function works well for div and not for table element.

html code:

<div class="one body" >
    sd
    </div>
<div class="two body">
    sddsd
</div>
    <table width="100%"  border="0" cellspacing="0" cellpadding="0" class="three body">jjj</table>

js:

$(".body").click(function(e){


    alert("xxxxxxxxx"+e.target.className);
});

Answer 1

Cause the actual e.target is a TD, not a table
Though you have an incorrect Table HTML Element structure. Tables are expected to have tr and td elements.

alert("Class: "+ event.target.className );

// is the Element that first fired the event ( TD )

alert("Class: "+ this.className ); 

// is the element that was delegated to the event, in this case .body

Answer 2

This is because your HTML is illegal. If you have illegal HTML, you should not expect your code to work properly.

Text may not be a direct child of a table . You need a tr and either a td or a th . The browser reinterprets your HTML and makes something legal. In this case, it puts the text outside the table:

    jjj
<table width="100%" border="0" cellspacing="0" cellpadding="0" class="three body"></table>

This is taken from Chrome's DOM inspector. The solution is to put the text legally inside the table .

Answer 3

Use this instead of e.target .

e.target will give you the clicked element, not the element where the event has been attached to. When the element where the event has been attached to has child-elements this and you click on a child-element e.target will return the child-element.

alert(this.className);

Answer 4

table elements cannot have any text content so, your html will actually be rendered as

  <div class="one body">
    sd
    </div>
<div class="two body">
    sddsd
</div>
    jjj<table class="three body" border="0" cellpadding="0" cellspacing="0" width="100%"></table>

Which is why your event handler is not firing when you click on jjj
