javascript - Javascript＆JQuery奇怪的问题还是我做错了什么？

我有此功能用于以一种方式工作的窗口之间的值，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？我在这里拔头发。

无法运作：

$(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;
        }
    });
});

我也尝试过

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

和..

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;

我没有为window.opener正确分配var吗？

最佳答案

var thisservice = document.forms['GroundRates']['service'];
var thisrate = document.forms['GroundRates']['rate'];
var thatservice = window.opener.document.forms['orderForm']['service'];
var thatrate = window.opener.document.forms['orderForm']['rate'];

thatrate.value = thatservice.value;
thatservice.value = thisservice.value;

或者如果您想用jQuery对象包装DOM对象。

var thisservice = document.forms['GroundRates']['service'];
var thisrate = document.forms['GroundRates']['rate'];
var thatservice = window.opener.document.forms['orderForm']['service'];
var thatrate = window.opener.document.forms['orderForm']['rate'];

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