使用JQuery动态创建不同的表

问题描述 投票：-3回答：2

我正在编写代码，我需要动态创建表。在这里，SO的一位专家帮助我创建它们，但在这里我正在寻找单独创建表格。

目前它就像

<table>
<tr>
<th></th>
<th></th>
<th></th>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<th></th>
<th></th>
<th></th>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<th></th>
<th></th>
<th></th>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
</tr>
</table>

但我想要它

  <table>
        <tr>
            <th></th>
            <th></th>
            <th></th>
        </tr>
        <tr>
            <td></td>
            <td></td>
            <td></td>
        </tr>
    </table>
    <table>
        <tr>
            <th></th>
            <th></th>
            <th></th>
        </tr>
        <tr>
            <td></td>
            <td></td>
            <td></td>
        </tr>
    </table>
    <table>
        <tr>
            <th></th>
            <th></th>
            <th></th>
        </tr>
        <tr>
            <td></td>
            <td></td>
            <td></td>
        </tr>
    </table>

这是工作小提琴。 http://jsfiddle.net/9r6a1uby/2/

请告诉我如何解决这个问题。

谢谢

使用下面的代码替换您的函数，这应该可以解决您的问题

HTML

<body onLoad="buildHtmlTable()">
   <div id="tables-div"></div>
</body>

JS

function buildHtmlTable() {
   for (var i = 0; i < myList.length; i++) {
       var $table = $('<table id="excelDataTable-'+(i+1)+'"  border="1"></table>');
       $('#tables-div').append($table);
       var columns = addAllColumnHeaders(myList[0], (i+1));

       for (var j = 0; j < myList[i].length; j++) {
           var row$ = $('<tr/>');
           console.log(myList[i][j])
           for (var colIndex = 0; colIndex < columns.length; colIndex++) {

               var cellValue =  myList[i][j][columns[colIndex]];

               if (cellValue == null) {
                   cellValue = "";
               }

               row$.append($('<td/>').html(cellValue));
               $("#excelDataTable-"+(i+1)).append(row$)
           }

       }
      $('#tables-div').append('<br />');
}


function addAllColumnHeaders(myList, table_id) {
    var columnSet = [];
    var headerTr$ = $('<tr/>');

    for (var i = 0; i < myList.length; i++) {
        var rowHash = myList[i];
        for (var key in rowHash) {
            if ($.inArray(key, columnSet) == -1) {
                columnSet.push(key);
                headerTr$.append($('<th/>').html(key));
            }
        }
    }
    $("#excelDataTable"+table_id).append(headerTr$);

    return columnSet;
  }
}
