jQuery：保留 .index() 返回每个父索引

发布于 2024-12-20 20:27:59 字数 941 浏览 3 评论 0原文

在下面的代码中，我试图获取单击的元素的索引，如果是，则获取其父索引。问题是它还尝试返回其父级的索引...

例如：如果我单击“1”，警报将返回 0,0 这很好。如果我点击 A2，警报将返回 0,1 （这也很好），然后返回 1,0 （父“坐标”）！！！我想保留它以返回父数组......

<ul>
    <li>1</li>
    <li>2
    <ul>
        <li>A2</li>
        <li>B2</li>
        <li>C2</li>
    </ul>
    </li>
    <li>3</li>
    <li>4</li>
    <li><5</li>
</ul>


$('#control ul li').click(function(e) { 
    e.preventDefault();

    var child = $(this).index(); // Get actual li element index
    var parent = $(this).parents('li').index(); // Get the later parent index
    if(parent === -1) { parent = 0; } // If it doesn't have a parent set -1 to 0
    var current = $.makeArray([child,parent]); // Make an array of the coordinate 

    alert(current);


    switcher(current);
});

In the code below, I am trying to get back the index of the element clicked and if so, its parent index. The problem is that it tries to return, also, its parent's index...

By example: if I click on "1" the alert will give back 0,0 which is good.
If I click on A2, the alert will return 0,1 (which is also good) and then return 1,0 (the parent "coordinate") !!!
I want to keep it to return the parent array...

<ul>
    <li>1</li>
    <li>2
    <ul>
        <li>A2</li>
        <li>B2</li>
        <li>C2</li>
    </ul>
    </li>
    <li>3</li>
    <li>4</li>
    <li><5</li>
</ul>


$('#control ul li').click(function(e) { 
    e.preventDefault();

    var child = $(this).index(); // Get actual li element index
    var parent = $(this).parents('li').index(); // Get the later parent index
    if(parent === -1) { parent = 0; } // If it doesn't have a parent set -1 to 0
    var current = $.makeArray([child,parent]); // Make an array of the coordinate 

    alert(current);


    switcher(current);
});

您应该停止事件传播。试试这个

$('#control ul li').click(function(e) { 
   e.stopPropagation();

   var child = $(this).index(); // Get actual li element index
   var parent = $(this).parents('li').index(); // Get the later parent index
   if(parent === -1) { parent = 0; } // If it doesn't have a parent set -1 to 0
   var current = $.makeArray([child,parent]); // Make an array of the coordinate 

   alert(current);


   switcher(current);
});

You should stop the event propagation. Try this

$('#control ul li').click(function(e) { 
   e.stopPropagation();

   var child = $(this).index(); // Get actual li element index
   var parent = $(this).parents('li').index(); // Get the later parent index
   if(parent === -1) { parent = 0; } // If it doesn't have a parent set -1 to 0
   var current = $.makeArray([child,parent]); // Make an array of the coordinate 

   alert(current);


   switcher(current);
});
