Chrome equivalent of Firefox Firebug CSS select path

由 久未见 提交于 2019-11-30 18:52:14
I've made the move to Chrome, but one of the most annoying features with 'Firebug lite' is that it doesn't allow you to copy the CSS path of objects. To see what I mean, in Firefox, go to google.com and inspect the logo with Firebug. Right click on the 'hplogo' div and pick 'Copy CSS path'. You'll get something like: html body#gsr div#main span#body.ctr-p center div#lga div div#hplogo This is an incredibly useful feature that I can't find on Chrome, it appears you can only copy the Xpath. Is there a way to use this type of functionality in Chrome? Thanks There is no native way to get this

I need to post data to a php page and then I'd like to get the text of a certain div that is in the response but I can't seem to set things up correctly. I'm not too good with jQuery but I can usually figure things out fairly quickly... I've been at this for a minute and have tried everything I have found... I think I am just missing the right combination of stuff. $.post("process.php", data , function (response) { var w = window.open(); $(w.document.body).html(response); console.log(typeof response); // yeilds string //create jquery object from the response html // var $data = $(response); //

Objective C >> Is there a way to check a Selector return value?

由 只愿长相守 提交于 2019-11-30 16:16:03
问题 let's say I have a selector that may be assigned to several different methods - each one has a different return value. Is there a way to check what is the return value of the method the selector is holding before calling "performSelector"? 回答1: Is there a way to check what is the return value of the method the selector is holding before calling "performSelector"? Value? No. Type? Yap. It seems that you want the return type of the method (or your question wouldn't make sense). Method m = class

Input type=file not working in WebView of OS X application

由 大憨熊 提交于 2019-11-30 15:54:48
问题 I have created an OSX application in Swift and embedded a WebView in it using Xcode 7. I have a file selector on the web page loaded by the WebView which asks the user to browse for a particular file from the user's computer. The problem I am facing is that nothing happens when the user clicks on the browse button. The same file selector control is working fine if i open the same web page in Safari. I am relatively new in swift, so help in this case would be appreciated. Here is my

Store selector as value in an NSDictionary

由 拟墨画扇 提交于 2019-11-30 11:07:54
问题 Is there a way to store a selector in an NSDictionary , without storing it as an NSString ? 回答1: SEL is just a pointer, which you could store in an NSValue : NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys: [NSValue valueWithPointer:@selector(foo)], @"foo", nil]; To get the selector back, you can use: SEL aSel = [[dict objectForKey:@"foo"] pointerValue]; 回答2: An alternative to Georg's solution would be to convert the selector into an NSString before storing it the NSDictionary

cancelling queued performSelector:afterDelay calls

由 馋奶兔 提交于 2019-11-30 10:15:43
问题 does anybody know if it is possible to cancel already queued selector events from the event stack or timer stack (or whatever mechanism it is that is utilized by the API) when you call performSelector:withObject:afterDelay ? I was using this event stack to alter the attributes of an image within a TabBar tab, and would sometimes queue up to 10 seconds worth of changes in one quickly executed for loop... maybe 5 milliseconds or so. the problem arises if the user switches tabs... like say I
