将表放入数组 [英] Put table in array

问题描述

嘿，我有一张桌子

<table>
  <tr>
    <th>Firstname</th>
    <th>Lastname</th> 
    <th>Age</th>
  </tr>
  <tr>
    <td>Jill</td>
    <td>Smith</td> 
    <td>50</td>
  </tr>
  <tr>
    <td>Eve</td>
    <td>Jackson</td> 
    <td>94</td>
  </tr>
</table>

我有一个要用此数据填充的数组:

And I have an array to be filled with this data:

    var params = {
        "fruit":"apple",
        "test": "Nope",
        "values": [
        [Here,Must  ,Come the header ],
        [Here,must come ,the first table data],
        [Here must,comt the ,second tabel data]
        ],
    }

这仅是1个表的示例 一些表包含更多行.

And this is just an example of 1 table some tables contain more rows.

如何确保整个数据都在数组中?

How can I make sure the whole data comes in the array ?

推荐答案

您需要嵌套循环才能获得所需的结果.参见下面的代码段

You need nested loops to achieve the required result. See the below snippet

 var params = {
        "fruit":"apple",
        "test": "Nope",
        "values": [
       
        ],
    }
    
    $(function(){
        $('button').click(function() {
            $("#mytable tr").each(function(index, item){
              var temp = []
              if(index == 0) {
                $(item).find('th').each(function(idx, col){
                    temp.push($(col).text());
                })
              }
              $(item).find('td').each(function(idx, col){
                temp.push($(col).text());
              })
              params.values.push(temp)
            })
             console.log(params);
        })
      
    })
    

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<table id="mytable">
  <tr>
    <th>Firstname</th>
    <th>Lastname</th> 
    <th>Age</th>
  </tr>
  <tr>
    <td>Jill</td>
    <td>Smith</td> 
    <td>50</td>
  </tr>
  <tr>
    <td>Eve</td>
    <td>Jackson</td> 
    <td>94</td>
  </tr>
</table>
<button>Click</button>
