大约一个月前,米特的问题没有得到答复.可悲的是,我现在遇到了同样的情况.

http://api.jquery.com/change/#comment-133939395

情况就是这样:我正在使用jQuery捕获单选按钮中的更改.选中单选按钮后,启用编辑框.取消选中单选按钮后,我希望禁用编辑框.

启用工作.当我在组中选择不同的单选按钮时,不会触发该change事件.有谁知道如何解决这一问题？

<input type="radio" id="r1" name="someRadioGroup"/> 

<script type="text/javascript">
    $("#r1").change(function () {
        if ($("#r1").attr("checked")) {
            $('#r1edit:input').removeAttr('disabled');
        }
        else {
            $('#r1edit:input').attr('disabled', true);
        }
    });
</script>

以下代码适用于Chrome,但不适用于IE或FireFox.有人知道相应的跨浏览器代码吗？

以下是JavaScript代码段...

<script src="http://code.jquery.com/jquery.min.js" type="text/javascript"></script>

var nodes;
if (typeof DOMParser != "undefined")
    nodes = ((new DOMParser()).parseFromString(request.responseText, "application/xml")).getElementsByTagName("*");
else {
    request.responseXML.loadXML(request.responseText);
    nodes = request.responseXML.getElementsByTagName("*");
} 

for (var i = 0; i < nodes.length; i++) {
    var element = nodes[i];
    ...
    if ((element.localName == "Body" …

我希望在第一个函数被调用之前,这个Dart程序中的整数'i'已被设置为9.但是这个程序的输出是......

0,2,4,6,8,10,12,14,16,18

当我通常预期10,11,12,13 ......就像JavaScript,C#等一样.

Dart Lang输出:0,2,4,6,8,10,12,14,16,18

typedef int TestFun(int x);

void main()
{
    List<TestFun> functionList = new List<TestFun>();

    for ( int i = 0; i < 10; i++) {        
        functionList.add( (int x) => x + i );      
    }

    for ( int j = 0; j < 10; j++) 
    {
        print(functionList[j](j));
    }    
}

等效JavaScript ....输出10,11,12 ...

var functionList = new Array;

for ( var i = 0; i < 10; i++) {
    functionList[i] = function (x) { return x + i …

我很难弄清楚如何使用ColorAnimation沿着可见的颜色光谱更改椭圆的填充颜色.ColorAnimation将颜色混合在一起而不是沿着色谱移动,所以我想出了以下内容.

<Ellipse x:Name="indicatorEllipse" HorizontalAlignment="Right" VerticalAlignment="Center" Height="20" Width="20" Stroke="Black" Margin="0 0 5 0" >
<Ellipse.Resources>
    <Storyboard x:Name="indicatorStoryboard">
        <!-- Animate the fill color of the Ellipse from red to green over 100 seconds. -->
        <ColorAnimation BeginTime="00:00:00" Storyboard.TargetName="indicatorColorBrush" 
Storyboard.TargetProperty="Color"
From="Red" To="OrangeRed" Duration="0:00:14" />
        <ColorAnimation BeginTime="00:00:15" Storyboard.TargetName="indicatorColorBrush" 
Storyboard.TargetProperty="Color"
From="OrangeRed" To="Orange" Duration="0:00:14" />
        <ColorAnimation BeginTime="00:00:30" Storyboard.TargetName="indicatorColorBrush" 
Storyboard.TargetProperty="Color"
From="Orange" To="Yellow" Duration="0:00:30" />
        <ColorAnimation BeginTime="00:01:01" Storyboard.TargetName="indicatorColorBrush"
