由 99封情书 提交于 2019-12-18 13:37:38
问题 Is there a way to find the selected text in an HTML document if the text may be within one of its frames (or iframes)? If the document has no frames it's simple: var text; if (document.getSelection) { // Firefox and friends text = document.getSelection(); } else if (document.selection) { // IE text = document.selection.createRange(); } if (text == undefined || text == '') { // Iterate over all textarea elements and see if one of them has selection var areas = document.getElementsByTagName(

Want to call a function if iframe doesn't load or load's?

问题 I have a iframe in my page. If the iframe doesn't load, want it to alert the message " pdf not found " and if the iframe does load, it should alert " pdf opened ". Does anyone know how to achieve that? 回答1: So, the idea is to use an Ajax-request to "test" the URL. Ajax-requests enable you to bind "success" and "error" handlers - unlike <iframe> elements which only provide a "load" handler. Of course, Ajax-requests are restricted by the Same Origin Policy (unless the web-server enables CORS),

问题 I try to add dynamically an iframe to a web page using JavaScript. I would like to know if that's possible to set the src attribute of my iframe without using another html file via an URL. I mean is there a way to "fake" the html for the src attribute file with a JS variable where we I can set my code (which is JS itself) ? I would use the DOM createElement to create the iframe in jQuery. Thanks ! 回答1: You could look into data:URIs. <iframe src="data:text/html, .... URLencoded HTML data ...."

问题 How can I dynamically post data to an iframe in Jquery. I really need to post data to an Iframe in this case, I cannot use a $.POST because data received is returned sequentially (buffered) If you have a workaround to make jquery handle data returned by a $.POST 'when it receives the data. I'm very curious! At the moment I handle it with GETS this way: var iframe = $('<iframe style="display:none;"></iframe>'); $( "body" ).append(iframe); iframe.attr('src','server.php?type=getFolders&inode='

问题 I doubt this is actually possible but Im prepared to be corrected.

Is this possible? 回答1: You can always get the web page dimensions, no matter if the page is loaded inside an iframe or a new window it always works the

iframe on iOS (iPad) content cropping issue

由 狂风中的少年 提交于 2019-12-18 11:47:09
问题 I'm looking for the correct way to assure that dynamically revealed content is visible after scrolling in an iframe on ipad / iOS5. Oh Iframes and iPad - what a wonderful old chesnut you are. I know that: iPad expands iframes to the full height of the content within it (almost like it was using HTML5's "seamless" property, but not quite since it doesn't inherit styles or events from the parent). Bizarre, annoying to many, but true. <iframe height="100%"> is therefore useless since it sizes to
