javascript - 如何使用 javascript 或 jquery 将 div 数据转换为数组？

Question

我想把这段代码转换成一个数组。

<div id="Parent">
     <div class="childOne" ><span id="1dfgdffsf">ChildOne </span></div>
     <div class="childOne" ><span id = "2sdfsf">ChildTwo</span> </div>
     <div class="childOne" ><span id="3sdfsf">ChildThree </span></div>
     <div class="childOne" ><span id="4dssfsf">ChildFour </span></div>
</div>

span id 是动态的。因此我不能使用它。请告诉我如何将它转换成数组。

你必须遍历每个元素并将其放入数组

//declare an array
var my_array = new Array();

//get all instances of the SPAN tag and iterate through each one
$('div#parent div.childOne span').each(function(){

    //build an associative array that assigns the span's id as the array id
    //assign the inner value of the span to the array piece
    //the single quotes and plus symbols are important in my_array[''++'']
    my_array[''+$(this).attr('id')+''] = $(this).text();

    //this code assigns the values to a non-associative array
    //use either this code or the code above depending on your needs
    my_array.push($(this).text());

});
