jquery attr A solution to the problem of & (macro) notation in SRC _jquery

Problem Description:

The HTML code is as follows:

<iframe src= "http://www.jb51.net" id= "Addorupdateiframe" style= "width:870px;height:450px" border= "0" scrolling= "Yes" ></iframe>

I set the src attribute of the IFRAME using the attr method of jquery

$ ("#addOrUpdateIframe"). attr ("src", "http://blog.jb51.net/search.aspx?key=400");/clickable link View effect note number of pages (show first page data)

No problem, I got the result I wanted, but the following address dropped the arguments behind the key (the red font parameter was not taken)

$ ("#addOrUpdateIframe"). attr ("src", "http://blog.jb51.net/search.aspx?key=400&page=2");/clickable link to view effect Note Number of pages (show second page data)


Depressed, feeling very strange, with Firebug looked at the modified value, the problem found, jquery to the above address to become:

http://blog.jb51.net/search.aspx?key=400&page=2//clickable Link View Effect Note page (show first page data)

In the middle of a depression ......

Looking for a long time also did not find if the problem, how he will address the & to change to & it? I don't know what I'm doing.

Problem Solving Method:

is inadvertently put

$ ("#addOrUpdateIframe"). attr ("src", "http://blog.jb51.net/search.aspx?key=400&page=2");/clickable link to view effect Note Number of pages (show first page data)

Change into

$ ("#addOrUpdateIframe"). attr ("src", ' http://blog.jb51.net/search.aspx?key=400&page=2 ');//clickable link to view effect Note Number of pages (show second page data)

Notice the gray background, change the double quotes into single quotes, and solve the problem.
