            return "<span title='" + value + "'>" + value + "</span>";  
        }  
  </script>  
2、调用函数

 <table class="easyui-datagrid" style="400px;height:250px"
    data-options="url:'datagrid_data.json',fitColumns:true,singleSelect:true">

其他方式：

1.例如，扩展 jQuery EasyUI tips

js 文件 Jquery.easyui.tooltip.js：

(function ($) {
    function init(target) {
        var opt = $.data(target, "tips").options;
        var tips = $(".easyui-tips-hover");
        if (tips.length == 0) {
            tips = $("<div/>").css({
                "position": "absolute",
                "border-radius": "5px",
                "-webkit-border-radius": "5px",
                "-moz-border-radius": "5px",
                "padding": "5px",
                "background": "#fff",
                "display": "none",
                "border": "1px solid gray"
            }).hide().addClass("easyui-tips-hover").addClass(opt.cls);
        }
    opt.content </span>= (opt.content || $(target).attr(<span style="color: #800000;">"</span><span style="color: #800000;">tooltip</span><span style="color: #800000;">"</span><span style="color: #000000;">));

}

})(jQuery);

使用:

在jquery 的datagrid的onLoadSuccess方法中

html:

<table id="dg"></table>

js :

$(function () {
            var _grid = $('#dg').datagrid({
                url: 'products.json',
                columns: [[
            { field: 'productid', title: 'productid',  100 },
            { field: 'productname', title: 'productname',  100 },
            { field: 'price', title: 'Price',  100, align: 'right' }
            ]],
                onLoadSuccess: function () {
                </span><span style="color: #0000ff;">var</span> tableTd = $(<span style="color: #800000;">'</span><span style="color: #800000;">div.datagrid-body td[field="productname"]</span><span style="color: #800000;">'</span>); <span style="color: #008000;">//</span><span style="color: #008000;"><span style="color: #800000;">productname</span>是列名</span>

                    tableTd.each(function () {

var $this = $(this);

var index = $this.parent('tr').attr('datagrid-row-index');

var rows = _grid.datagrid('getRows');

var currentRow = rows[index];

var content = '<div style=" max-700px;word-break: break-all; word-wrap: break-word;">' + currentRow.productname + '</div>'; //productname是列名

$this.tips({ content: content, wrapColor: 'black' });

});

}

});

});
