相当简单的 JQuery 输入选择位置问题
我在将 JQuery javascript 代码应用到它应该应用的选择框元素时遇到问题。发生的情况是选择框没有遵循 javascript 代码中指定的操作。它们只是保持禁用和选中状态(请参见下面的代码),而不是根据第一个复选框的选择进行更改。
我相信这是一个关于如何在 javascript 代码中指定选择框的位置的问题,但我不知道如何修复它。话又说回来,我的看法也可能是错的。
如果您对此有任何见解或可以更正代码,请这样做!干杯。
HTML:
<div class="medium_box">
<form name="searchform" class="FECKsearch" method="get" onSubmit="return dosearch();">
<input name="s" id="searchBox" class="input" type="text" value="" onfocus="myFocusHandler(this);" onblur="myBlurHandler(this);" size="18" maxlength="50">
<input type="submit" name="searchsubmit" class="button" value="Go" />
<span class="searcher">International: <input type="checkbox" id="International" checked="yes"></input></span>
<span class="searcher1">Americas: <input type="checkbox" id="Americas" disabled checked="yes"></input></span>
<span class="searcher1">Europe: <input type="checkbox" id="Europe" disabled checked="yes"></input></span>
Asia: <input type="checkbox" id="Asia" disabled checked="yes"></input>
</form>
</div>
Javascript:
$('#International').click(function() {
var paramChangeBoxes = $('input:checkbox');
if ($(this).is(':checked')) {
$('#Americas').attr('checked', 'checked');
$('#Americas').attr('disabled', 'disabled');
$('#Europe').attr('checked', 'checked');
$('#Europe').attr('disabled', 'disabled');
$('#Asia').attr('checked', 'checked');
$('#Asia').attr('disabled', 'disabled');
}
else {
paramChangeBoxes.removeAttr('disabled');
$('#Americas').removeAttr('disabled');
$('#Europe').removeAttr('disabled');
$('#Asia').removeAttr('disabled');
}
});
更新和解决方案:
为 John 的代码干杯 $('#International').live("click",function () {
纠正了 JQuery 代码无法运行的错误。显然,如果您从远程文件导入代码,则必须在编码中包含“实时”部分。
再次感谢约翰!
I am having a problem with getting my JQuery javascript code to apply to the select box elements that it is supposed to. What's happening is that the select boxes are not following the actions that are specified in the javascript code. They are simply staying disabled and checked (see code below) instead of changing based on the first checkbox's selection.
I believe it is a problem regarding how I specify the location of the select boxes in the javascript code, but I don't know how to go about fixing it. Then again, I could be wrong about that too.
If you have any insight on this or can correct the code, please do! Cheers.

$('#International').click(function() {
var paramChangeBoxes = $('input:checkbox');
if ($(this).is(':checked')) {
$('#Americas').attr('checked', 'checked');
$('#Americas').attr('disabled', 'disabled');
$('#Europe').attr('checked', 'checked');

}
else {
paramChangeBoxes.removeAttr('disabled');
$('#Americas').removeAttr('disabled');
$('#Europe').removeAttr('disabled');
$('#Asia').removeAttr('disabled');
}
});
Update & Solution:
Cheers to John for the code $('#International').live("click",function() {
which corrected the error of the JQuery code not functioning. Apparently if you are importing the code from a remote file you must include the "live" portion inside of your coding.
Thanks again John!

下面的代码还有很大的空间可以加强,但它是有效的:
There's a lot of room for tightening the following code up, but it works:
