jQuery的每个填充元素逐渐从数组

Question

Hello I would like to fill gradually span elements with values of array. Can you help me please?

<span class="gt"></span>
<span class="gt"></span>
<span class="gt"></span>

var array=["apple","banana","cucumber"];

$("span.gt").each(function(){
    $(this).text(array[?]);
});

Output should look like this:

<span class="gt">apple</span>
<span class="gt">banana</span>
<span class="gt">cucumber</span>

Answer 1

You get the index value in the function for each loop. And since the number of span elements is equal to the number of items in the array variable you can use that index value to set the array values in the span elements:

 var array=["apple","banana","cucumber"]; $("span.gt").each(function(index){ $(this).text(array[index]); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <span class="gt"></span> <span class="gt"></span> <span class="gt"></span> 

Answer 2

1. You can use for loop.
2. Use the increment number as index of the span and index of array

 var array = ["apple", "banana", "cucumber"]; for (var i = 0; i < array.length; i++) { $('span').eq(i).text(array[i]); } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <span class="gt"></span> <span class="gt"></span> <span class="gt"></span>
