有时候我们需要对不同数据的背景色加以区分，简单例子是将用户希望一眼看出来的数据加重颜色。

　　思路:根据不同的状态修改每行开始的tr的背景色.

var tr_start = papers[i].usetimes > 0 ? ""                : "";

 

 

例子:

// 填充表格function showTable(data) {    var result = eval("(" + data + ")");    $("#paperTableBody").html("");// 清空表    var papers = result.pageBean.productList;    for (var i = 0, length = papers.length; i < length; i++) {        var index = (result.pageBean.currentPage - 1) * 8 + i + 1;        var tr_start = papers[i].usetimes > 0 ? ""                : "";        $("#paperTableBody")                .append(                        tr_start                                + ""                                + index                                + ""                                + papers[i].title                                + ""                                + papers[i].level                                + ""                                + papers[i].paperscore                                + ""                                + papers[i].usetimes                                + ""                                + papers[i].description                                + ""                                + papers[i].employeename                                + ""                                + papers[i].maketime                                + ""                                + "修改删除试卷预览"                                + "");    }

 

结果:
