We need to post to a search web application and have it display the results in a new window. Can the SharePoint 2010 HTML Form Web Part do this? Any examples? Thanks.
This does the job: http://code.google.com/p/jquerysharepointform/ It even lets you define whether to pop the form up in a new window or to do a POST or GET. You just have to ensure jQuery is loaded, then call the function:
I go a step further and also call the submit if the user hits enter in the input field. Put the whole thing in a content editor web part and you're off and running. The SharePointFormSubmit function replaces the DIV wrapper with a form and submits the information.
Hope this helps others.
