在for循环内使用jQuery.each将数组映射到元素文本？

Question

for the given html:

<div id="parent">
    <div class="child">x</div>
    <div class="child">y</div>
    <div class="child">z</div>
</div>

How can I map the text of its children from an array?

This is my try:

var myArray = ['a', 'b', 'c'];

for (var i = -1; i < myArray.length; i++) {
    $('#parent .child').each(function () {
        $(this).text(myArray[i]);
    });
}

I get: c,c,c

How can I get a,b,c ?

Answer 1

You don't need the outer for loop:

var myArray = ['a', 'b', 'c'];

$('#parent .child').each(function (index) {
    $(this).text(myArray[index]);
});

Answer 2

There's no need to use for loop here.

 var myArray = ['a', 'b', 'c']; $('#parent').find('div').each(function(){ $(this).html(myArray[$(this).index()]); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="parent"> <div class="child">x</div> <div class="child">y</div> <div class="child">z</div> </div> 

Answer 3

Use .text(function)

 var myArray = ['a', 'b', 'c']; $("#parent > .child").text(function(index) { return myArray[index] }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"> </script> <div id="parent"> <div class="child">x</div> <div class="child">y</div> <div class="child">z</div> </div>
