I want to get width and height of HTML element because I want to use these information to segment and analyse a web page. I searched an answer in FAQ of Gecko. It tells that Gecko can get these information easily. But I am a beginner of Gecko and don't want to dive into it. It seems hard even trying to compile it. Could anyone help me to achieve my goal ? Where should I get started? Thanks.
https://wiki.mozilla.org/Gecko:Frequently_Asked_Questions Q. Can I use the Gecko engine to get the width information of some HTML elements (such as table,tr,td)? The element width information is not always available in the HTML source, but when the element is displayed, the width information is required. I think the layout engine calculates the width. Is there a way to retrieve the width of the element from the layout engine? A. All HTML elements have offsetWidth and offsetHeight properties (see http://developer.mozilla.org/en/docs/DOM:element.offsetWidth and http://developer.mozilla.org/en/docs/DOM:element.offsetHeight). You can also use getComputedStyle (http://developer.mozilla.org/en/docs/ DOM:window.getComputedStyle) to get width/height information. You can also use the DOM Inspector in Firefox to view computed style. _______________________________________________ dev-tech-layout mailing list [email protected] https://lists.mozilla.org/listinfo/dev-tech-layout
