Javascript 和 JQuery 奇怪的问题或者我做错了什么？

Question

我有这个函数来处理从一个窗口到另一个窗口的值，它以一种方式工作，但不是另一种......

工作脚本:

$(document).ready(function(e) {
    $('#clickit').live({
        click: function() { 
            window.opener.document.forms['orderForm']['service'].value = document.forms['GroundRates']['service'].value;
            window.opener.document.forms['orderForm']['rate'].value = document.forms['GroundRates']['rate'].value;
            self.close();
            return false;
        }
    });
});

现在我在另一个脚本上，我做错了什么？我要在这里拔掉我的头发。

不工作:

$(document).ready(function(e) {
    $('#clickit').live({
        click: function() { 
            var thisservice = document.forms['GroundRates']['service'].value;
            var thisrate = document.forms['GroundRates']['rate'].value;
            var thatservice = window.opener.document.forms['orderForm']['service'].value;
            var thatrate = window.opener.document.forms['orderForm']['rate'].value;
            $(thatrate) = $(thisrate);
            $(thatservice) = $(thisservice);
            self.close();
            return false;
        }
    });
});

我也试过了..

$(thatrate).val() = $(thisrate).val();
$(thatservice).val() = $(thisservice).val();

还有..

thatrate = thisrate;
thatservice = thisservice;

但这有效:

var service = document.forms['GroundRates']['service'].value;
var rate = document.forms['GroundRates']['rate'].value;
window.opener.document.forms['orderForm']['service'].value = service;
window.opener.document.forms['orderForm']['rate'].value = rate;

我是否没有为window.opener正确分配变量？

Answer 1

您滥用了 .val()

$(thatrate).val($(thisrate).val());
$(thatservice).val($(thisservice).val());

新值位于括号内。
