Variable as jQuery selector focus
I'm using JavaScript to copy a specific div from a page into a new page. I need to remove the ID attributes for each table in the new page.
It seems that since I'm copying content from the first page, I can filter out the IDs from the string before it is written to the second page. Can jQuery take a variable as its 'focus'? Instead of manipulating the entire DOM, manipulate a particular string?
I have a non-working version of what I'm talking about:
var currentContent = window.open('','currentContentWindow');
var htmlToCopy = '<html><head><title></title></head><body>' + window.frames[0].document.getElementById('PageContentPane').innerHTML + '</body></html>';
$("table", htmlToCopy).removeAttr('id');
currentContent.document.open();

currentContent.document.close();
You need to create a jQuery object by calling $(html), manipulate it, then get the HTML back by calling html().
For example:
var currentContent = window.open('','currentContentWindow');
var htmlToCopy = '<html><head><title></title></head><body>' + window.frames[0].document.getElementById('PageContentPane').innerHTML + '</body></html>';
var newStructure = $("<div>" + htmlToCopy + "</div>");
newStructure.find("table").removeAttr('id');
currentContent.document.open();
currentContent.document.write(newElements.html());
The <div> element allows me to get its inner HTML and get the HTML you're looking for.
Who not just remove ID= as a string and forget DOM manipulation all together?
First make the string a jQuery object, then work with it:
htmlToCopy = $(htmlToCopy).find("table").removeAttr('id').end().html();
