这是我的html的基本视图:
<form>
<div id="part1">
// some html form elements including checkboxes
</div>
<div id="part2">
// more html code with more checkboxes
</div>
<div id=part2">
// data table with numerous checkboxes built dynamically
</div
</form>
我需要做的是将.click()事件分别绑定到第1部分,第2部分和第3部分中的复选框.我试过这个$('#part1:checkbox').click(...)但是没用.如果我使用$("form :checkbox").click(...)相同的点击事件绑定到所有复选框而不仅仅是一组.我怎么分开这些？
我想做的事情:正如标题中所述,我想设置一个单词的CSS,如果它是一个保留字.
<html>
<body>
<code id="java">
public static void main(String[] args)<br>
{
<pre> System.out.println("Hello World!");</pre>
}
</code>
</body>
</html>
$(document).ready(function()
{
// Get the text inside the code tags
var code = $("#java").text();
// Split up each word
var split = code.split(' ');
// Array of reserved words
var array = ["abstract","assert","boolean","break","byte","case",
"catch","char","class","const","continue","default",
"do","double","else","else if","enum","extends","final",
"finally","float","for","goto","if","import","implements",
"instanceof","int","interface","long","native","new","null",
"package","private","protected","public","return","short",
"static","strictfp","super","switch","synchronized","this",
"throw","throws","transient","void","volatile","while"];
// Added when text contains a reserved word
var css = {'font-weight':'bold','color':'#2400D9'}
array = jQuery.map(array, function(n,i)

for …我正在开发一个项目,需要我配置gpio引脚并在原子板上添加传感器.内核配置了gpio ... CONFIG_GPIO_SYSFS=y是内核选项之一.
我正在使用Fedora版本2.6.29-10
但是我无法写入gpio文件夹中的导出文件
GPIO=22 // to add pin 22 to userspace
echo $GPIO > /sys/class/gpio/export
我收到了错误
bash: echo: write error: Invalid argument
我也试过同样与sudo和sh -c,但没有用,除非我可以公开这些引脚用户空间,我不能写任何code.What我做错了什么？
是否需要设置内核版本或其他一些内核选项的问题？

我试图打开AlertDialog另一个AlertDialog,但它不起作用,任何想法为什么它不起作用？
String items[] = {"Details","Edit","Delete"}
AlertDialog.Builder alert = new AlertDialog.Builder(getAplicationContext());
alert.setTitle("Options");
alert.setItems(items, new OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
switch(item){
case 0:
AlertDialog.Builder alert2 = new AlertDialog.Builder(getAplicationContext());
alert2.setTitle("Details");
alert2.setMessage(getDetails());
alert2.setNeutralButton("Close", null);
alert2.show();
return;
case 1:
//not important for the question
return;
case 2:
//not important for the question
return;
}
}
});
alert.setNegativeButton("Cancel", null);
alert.show();
a has_many Bs
B has_many Cs
B belongs_to A
C belongs_to B
C belongs_to A.
但是当我这样做时myA.to_json(:include => [:b, :c]),一切都处于最高级别,这是有道理的,但是如何将params传递给to_json,使得Cs将位于B下的数组中,而不是A？
我认为它看起来应该是这样的:myA.to_json(:include => [:b => :c])
我将这个看作myA,json,同时包括b,其中包括c.
我有关于在Objective-C中分配属性的以下问题,
如果我有以下财产:
@property (nonatomic, retain) NSArray *arr;
@synthize arr=_arr;
我应该像这样分配这个数组:
arr=[[NSArray alloc]init];
如果我愿意,分配它的最佳位置在哪里？
我知道我应该释放它,但是保留一个属性会使其保留计数增加1并且分配它会使它增加1,我是对的.
我有一个popover,显示一个包含几个单元格的tableview.触摸单元格时,它会调用以下代码:
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(@"Cell check %@", [totalArray objectAtIndex:indexPath.row]);
[self dismissPopoverAnimated:YES];
}
我知道这个方法被调用,因为NSLOG显示它应该的文本.问题是弹出窗口没有被解雇.我以为
[self dismissPopoverAnimated:YES];
应该解雇popover？我究竟做错了什么？
