数据表 - 单元格字符串截断

时间：2015-08-04 12:55:19

标签： jquery json datatables

我正在使用jQuery DataTables在表中显示数据，并使用AJAX链接将表内容加载到已嵌入对象的文件JSON

我有一个列，其中包含一个字符串，我想给格式化，并且我想剪切链并添加三个最终点，以防万一超出字符限制。

我已经在几次使用JavaScript函数完成了这项工作，但现在因为它将通过JSON加载我不知道该怎么做

有什么建议吗？

解

您可以使用columnDefs定位具有targets选项和render的特定列，以便在显示数据时呈现列内容（type === 'display'）。

样本

// Truncate a string
function strtrunc(str, max, add){
   add = add || '...';
   return (typeof str === 'string' && str.length > max ? str.substring(0, max) + add : str);
};

$(document).ready( function () {
  var table = $('#example').DataTable({
     'columnDefs': [
        {
           'targets': 1,
           'render': function(data, type, full, meta){
              if(type === 'display'){
                 data = strtrunc(data, 10);
              }
             
              return data;
           }
        }
     ]
    
  });
});

答案 1 :(得分：3)

我遇到了同样的问题并使用mRender

解决了这个问题 
"mRender": function(data, type, row) {
    var trimmedString = data.substring(0, 6);
    return trimmedString + '...';
  }

答案 2 :(得分：1)

可以使用渲染限制内容

{
    data:'content_body',
    render: function(data){
        if(data){
            return (data.length > 200)?data.substring(0, 200)+'...':data;
        } else {
            return '';
        }
    },
},

也许您可以使用名为省略号的插件（作者：Allan Jardine）。 Here，您可以找到更多信息。
