javascript - How to Access iFrame Checkbox Elements -

-

Can anyone tell me if I have a web page that has the checkbox (parent) and this web On the page, I also have an IFrame that comes from another page which displays many records, in which each record also has a checkbox (children), if I stick to the parent checkbox, then I have all children Iframe want to cascade in check box You can also disable these children's checkboxes as well as within.

In fact, may appreciate some help with this because I'm not sure how to use the check box within the iframe.

My iframe definition man page is similar to: 

  & lt; Iframe id = "iframe1" src = "'+ url +' style =" border: none; Width: 79 9px; Height: 200px; "Frameborder =" 1 "fraszing =" 0 "margin width =" 0 "margin width =" 0 ">

Any example / website

Thanks Tony.

OK, here's an example. First of all, here is the source for iframe content (I called it frame page html) ... 

  & lt; body & gt; & lt; input id = "Checkbox 1" type = "checkbox" name = "checkbox" /> Input ID = "checkbox2" R = "checkbox" name = "checkbox" /> input id = "checkbox 3" type = "checkbox" name = "checkbox" />

Here is the source on the page that holds the iframe ... 

  iframe id = "frame" src = "frame page. HTTM "& gt; & lt; / iframe & gt; & lt; input id =" button1 "type =" button "value =" button "onclick =" setData () "/> & gt; & gt; script type = "Text / JavaScript" & gt; Function SetData () {var frame = document.getElementById ('frame'); var checkbox = frame.contentWindow.document.getElementsByName ('checkbox'); for (var i = 0; i & Lt; checkbox length; i ++) {checkbox [i]. Checkeded = true;}}

clicking the button on the parent page All checkboxes will be selected on the frame page with the name 'checkbox'.

Hopefully this :)

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
