jquery - 将所有表 td 值放入数组中

Question

我需要将所有 td 值放入字符串数组中。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。

尝试这样:

$('#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']

});
