阅读更多关于 jQuery: How to get parameters of a url?

问题 New to jQuery and I'm having trouble getting the parameters of a url that my server generates. I have a url like this: <span class="popuptest"><a href="www.example.com/test?param1=1&param2=2">find param</a></span> my jquery function looks like so: $(function() { $('.popuptest a').live('click', function(event) { $.extend({ getUrlVars: function(){ var vars = [], hash; var hashes = this.href.slice(this.href.indexOf('?') + 1).split('&'); for(var i = 0; i < hashes.length; i++) { hash = hashes[i]

How can I send POST and GET data to a Perl CGI script via the command line?

阅读更多关于 How can I send POST and GET data to a Perl CGI script via the command line?

问题 I am trying to send a get or a post through a command-line argument. That is test the script in the command line before I test through a browser (the server has issues). I tried searching online, and I suppose I was probably using incorrect terminology because I got nothing. I know this is possible because I saw someone do it. I just don't remember how it was done. Thanks! :) 回答1: Are you using the standard CGI module? For example, with the following program (notice -debug in the arguments to

Use jQuery to get the file input's selected filename without the path

阅读更多关于 Use jQuery to get the file input's selected filename without the path

I used this: $('input[type=file]').val() to get the file name selected, but it returned the full path, as in "C:\fakepath\filename.doc". The "fakepath" part was actually there - not sure if it's supposed to be, but this is my first time working with the filename of file uploads. How can I just get the file name (filename.doc)? var filename = $('input[type=file]').val().split('\\').pop(); or you could just do (because it's always C:\fakepath that is added for security reasons): var filename = $('input[type=file]').val().replace(/C:\\fakepath\\/i, '') You just need to do the code below. The

How to set $_GET variable

阅读更多关于 How to set $_GET variable

问题 How do i set the variable that the $_GET function will be able to use, w/o submitting a form with action = GET ? 回答1: You can create a link , having get variable in href. <a href="www.site.com/hello?getVar=value" >...</a> 回答2: $_GET contains the keys / values that are passed to your script in the URL. If you have the following URL : http://www.example.com/test.php?a=10&b=plop Then $_GET will contain : array 'a' => string '10' (length=2) 'b' => string 'plop' (length=4) Of course, as $_GET is

Beautiful way to remove GET-variables with PHP?

阅读更多关于 Beautiful way to remove GET-variables with PHP?

I have a string with a full URL including GET variables. Which is the best way to remove the GET variables? Is there a nice way to remove just one of them? This is a code that works but is not very beautiful (I think): $current_url = explode('?', $current_url); echo $current_url[0]; The code above just removes all the GET variables. The URL is in my case generated from a CMS so I don't need any information about server variables. Justin Ok, to remove all variables, maybe the prettiest is $url = strtok($url, '?'); See about strtok here . Its the fastest (see below), and handles urls without a '

Why shouldn't data be modified on an HTTP GET request?

阅读更多关于 Why shouldn't data be modified on an HTTP GET request?

I know that using non-GET methods (POST, PUT, DELETE) to modify server data is The Right Way to do things. I can find multiple resources claiming that GET requests should not change resources on the server. However, if a client were to come up to me today and say "I don't care what The Right Way to do things is, it's easier for us to use your API if we can just use call URLs and get some XML back - we don't want to have to build HTTP requests and POST/PUT XML," what business-conducive reasons could I give to convince them otherwise? Are there caching implications? Security issues? I'm kind of
