javascript - 如何以指定方式动态创建数组

Question

我有多个来自数据库的值，它随着新记录的添加而增加。

我正在做这样的跨度:

<span style="display:none;" class="skills"  data-skill="php programing">350</span>

<span style="display:none;" class="skills"  data-skill="java programing">235</span>

<span style="display:none;" class="skills"  data-skill="python programing">289</span>

我想用这种方式构造一个数组

var data = google.visualization.arrayToDataTable([
          ['jobs', 'Jobs Available'],
          ['php programing',     350],
          ['java programing',     235],
          ['python programing',  289]
        ]);

这样我就可以动态构建一个谷歌饼图

现在我正在做这样的事情

arrayToDataTable = [];
arrayTemp = [];
$.each('.skills',function(i){
 var skill = $(this).data('skill');
 var number = $(this).text();
  arrayTemp.push(skill);
  arrayTemp.push(number);
  arrayToDataTable.push(arrayTemp);
});


**my question how can i make array in this fashion dynamically:**

     [
          ['jobs', 'Jobs Available'],
          ['php programing',     350],
          ['java programing',     235],
          ['python programing',  289]
       ]

请帮我提前谢谢

Answer 1

arrayToDataTable = [];

$.each('.skills',function(i){
 var skill = $(this).data('skill');
 var number = $(this).text();
  arrayToDataTable.push([skill, number]);
});

console.log(arrayToDataTable);

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

<span style="display:none;" class="skills"  data-skill="php programing">350</span>

<span style="display:none;" class="skills"  data-skill="java programing">235</span>

<span style="display:none;" class="skills"  data-skill="python programing">289</span>

你试过吗:

arrayToDataTable.push([arrayTemp])
