Change Checkbox Checked Value based upon variable passed by href

问题

Using Javascript and HTML Form

Page 1: Simple Link passing two variables (page1var1=xxxx and page1var=yyyy) separated by an "&" symbol

Page 2: Use Javascript to "split" the two variables either side of the "&" into page2var1 and page2var2

So now page2var1=xxxx and page2var2=yyyy (successfully done already)

How do I use these variables in page 2 to:

1. Check a form input checkbox (i.e. "put a tick in the box") which has the ID/Name) Page2var1 (i.e. xxxx)
2. Put the variable page2var2 (i.e. yyyy) into the value of a fixed form textarea

回答1:

Something like this:

document.GetElementById(Page2var1).checked = true;
document.GetElementById(page2var2).value = 'whatever text'

Nothing google wouldn't help you with.
