lt script type  text javascript  gt    document write        lt iframe id  myframe  src  http   www example com          window location search      height  100  width  100    gt         lt  script gt      This code takes the url-parameters   a 1 amp b 2  from the page containing the iframe and attaches them to the base url of the iframe  It works for my purposes

While generating the links set the target to the iframes name property and you probably wont have to deal with jquery at all    lt a href  inventory aspx  target  contentframe   title  Title Inventory  gt   lt iframe id  iframe1  name  contentframe    gt  lt  iframe gt

if you are using jQuery 1 6 and up  you want to use  prop   rather than  attr         abc frame   prop  src   url    See this question for an explanation of the differences

Use attr      abc frame   attr  src   url    This way you can get and set every HTML tag attribute  Note that there is also  prop    See  prop   vs  attr   about the differences  Short version   attr   is used for attributes as they are written in HTML source code and  prop   is for all that JavaScript attached to the DOM element

You cannot set FIX iframe s src or prevent javascript form submit to change its location  However you can put script to onload of the page and change action of each dynamic link
