HTML table implements double-click to open the edit box, lose focus and save

html:

<td ondblclick="zdyEditTableCell(this,'<s:property value="#l.id"/>','sums')"><s:property value="#l.sums" /></td>

JS:

/**
 * html的table双击打开编辑框(原始的table的单元格td的ondblclick事件)
 * @param element 表格的td
 * @param id 指标indexItems的id值
 * @param field 表示的是indexItems的哪个属性值被修改
 */

    var str = "<input type='text' class='edit' name='test' style='width:90%' onblur='inputBlurFun(this,"+id+",\""+field+"\","+oldhtml+");' value='"+oldhtml+"'/>";
    
    $(element).text('');
