jquery – 将所有表td值转换为数组

我需要将所有td值都放入字符串数组中.以下是我的代码

var tr = "#tblPurchaSEOrders tr.PO1";

     $(tr).each(function(index,tr) {
                    var lines = $(tr + " td").map(function(ind,td) {
                        var ret = {};
                        ret[ind] = $(td).text();
                        return ret;
                    }).get();

    // I need to some more thing here 

    // I need to store all the td values in to lines variable.. This is not working for me.
    // Am I missing some thing?

    });

谢谢.

解决方法

试试这样：

$('#tblPurchaSEOrders tr.PO1').each(function(index,tr) {
    var lines = $('td',tr).map(function(index,td) {
        return $(td).text();
    });
    // Here lines will contain an array of all td values for the current row:
    // like ['value 1','value 2','value 3']

});
