I am building a forum and I am experienced in PHP, MySQL and even in jQuery now somewhat, but I have run into something I just can't seem to find the answer too. Here is a simple example which I think contains everything you need to know. If I have 10 elements on a page, say 10 divs, and I want to hide the odd ones, I would just use $("div:odd").hide() and wrap it into the document.ready function. The page loads, the divs are hidden, awesome. However, let's say that after the ten divs, there is a link which triggers an AJAX request and the return data is basically another 10 divs which get pasted under the ones already on the page.
What I would like to happen is that the script I wrote a paragraph ago kicks in and hides the odd divs automatically. Now it makes sense that this does not happen, since it seems logical that when the page loads, the script parses the divs and hides stuff, so after I get the AJAX results it won't do it again. What IS weird to me is that the functions I defined don't work either, so if I define
$("div").click(function() {SOMETHING HERE})
It will work for the first set of elements, but not for the ones which are returned by the AJAX call.
I am currently using $.ajax to post to a Perl file that queries a webservice and returns XML. Running the Perl via command line confirms that XML is being returned with Content-Type: application/xml. However, regardless if I set the dataType parameter to "xml", "XML" or just use jQuery's intelligent guess, it appears that I am not getting any data returned to my function at all.
I've tried using the full $.ajax notation and the simplified $.get notation as follows:
and:
I have also tried using JQuery to perform a "GET" directly to the webservice which returns XML by default and still I get no data returned to my function.
Although I doubt it's browser-related, I have confirmed this in both Chrome (5.0.375) and Firefox (3.6.3).
I have a problem with returning html data from an ajax request. I have php method which is called via ajax and returns a long html string which consists of multiple tables, each table represents one question in a questionnaire. They display fine. I then have a button which calls a second php method that returns one individual table - identical in structure to the multiple tables that were returned previously. However,when displayed,the new table has the an inline style "display:block;" and so it screws up the way it looks. I have, at no point, declared this additional style anywhere in my code. Even if I do add an inline style of "display:table;" to the returned html, it is overwritten in the output html - so it is clearly being done by javascript.
I'm having a little problem with a jQuery/JS script I just wrote in IE7/8. The problem is the first 2 lines of the returned data are not being displayed (w or wo styling) but only in IE. The strange thing is though if I alert the returned data it's there.
I am building a large registration form. In this form, a sponsor/educator must register himself or herself and then may add up to 6 more " delegates" in pairs. The first two pairs registration info on the form is shown by default. I need to hide the other two pairs until when/if the user clicks on a button to add two more delegates at a time. I used javascript to show or hide the parts of the form that I had put into two divs and adjusted the css display attribute. However, my problem was that, if the user filled out the sponsor/educator section and the first two delegates, and then decided to add two more, when the user clicked on the button to show the part of the form for delegates 3 and 4, it reset all the previous visible form fields to empty. Not good. So, I thought, maybe AJAX.
I created the request object (I am a relative novice at AJAX), had it grab a text file with the code to insert into my target div, in this case a div with id = "delegate3and4". Surprisingly however, it still reset the previous form fields to empty. Am I misunderstanding how AJAX is supposed to work? I figured that, because it does not refresh the page that this would not happen. In fact, to test this out, I created a simple page from scratch with just a single input field and then used AJAX to insert the file in a div after this field and it did not reset the previous input. So, I am totally confused about why this would be happening on my live page. The page is a php page as it submits the form to a php script for processing but I don't think this should make a difference.
I'm looking for some javascript to work with wordpress (jQuery preferrably) that will show/hide multiple divs on one click.
I had one working but it was kinda janky because it was causing me to have two divs with the same ID on one page. No good.
Since I updated to wp2.8.3 prior to launch, it's not working. So I've decided to just try and do it right.
Here's a page: [URL]
So, what I want to happen: On page load, the first tab: "general" and it's corresponding div beneath should be showing. And the first image should be showing. The other content divs and images should be hidden. I've given the text content divs a dashed border to show their borders. When a visitor clicks "dine at home" the general div and image hide, the second content div shows, as does the second image (it's currently the identical image, but the client may change later.) Etc.
I'll be using this function on a few other pages as well.
how to adjust this javascript to work on two different IDs at once?
I am using an webservice(.net) to do some database related operations. I would like to call a method from this webservice to return an xml file. At the client side I want to use jquery to call this webservice by passing json object. How will I do this? In success method is it possible to get the xml file as returned value from the webservice?
What I have is a normal ASP web page wih javascript. The javascript needs to call a payment gateway, but the only way to get to it is https://paymentgateway/external.pl with parameters.
What is returned is a string containing several lines of information. This information I need to formulate into my own page..
At present, I use document.location = https..... but of course this displays the called page (above) in the browser screen with the results.
Im sure this can be done, but how can I call this gateway webpage without showing it (so the user would just see my please wait page) and retrieve the data when it comes back (within 6 secs).
So I'm loading the div#my_events by prepend(data) where "data" is another well styled div. Is there anyway to animate this returned data. Unfortunately I can't just specify a unique ID on the incoming data. So I was wondering how else I might be able to address this data I'm returning.
It is basically a topic list, with a modal that sends jquery to add a topic to the database, and returns the topic from the database, hides the modal, and displays the last added topic at the top of the topic list. Now I'd like it to do something slightly fancy like animate the color of the background to bring the user's attention to it.
I define a "click" event on "a" tags in the ready part of a page. It fires just fine when I click on any "a" tag on the page. I then have a button which sets the content of a div using ajax. This content contains a couple of "a" tags. The issue now is that the "click" event does NOT fire when clicking on these tags. I suspect it is because they did not exist when the page was initially rendered. What is the "JQuery way" of dealing with an issue like this? Of course I cannot be the only one in the world who needs to return HTML with events from my ajax calls :-)
In this dumb example, I'm unable to match the 'data' returned variable with the value I assigned to it in php (I can't manage to enter my 'do stuff'), yet its value is 'ok' if I display it. I have no problem to retrieve html code from php and inject it in my pages, but I can't test it as a regular javascript string.
What's wrong in this ? What have I missed about the 'data' format ? Do I have to 'cast' data to a javascript string (and if so, how ?)
but this has not worked. the latter showed that jquery is inserted in the index. the main page that calls the button. jquery in a home can act on an ID loaded from another file with ajax?
I have a problem I have in my controller a function which poperly returns the value (i've checked by var_dump). When I try to access this data from $.ajax it returns nothing...
I'm currently working on a form where an entire HTML page is returned via the .ajax method. I would like to display only the content of the div with the id "content" (of the page returned) in the div with the id "result" (in the calling page). Here is my current script :
I have a div container that is used to specify where the table I retrieve via ajax is placed $("#div_reveal").html(AjaxResponse). I have tried to add an onSuccess function to update the table function (){ $("table").trigger("update"); } but the table does not sort. When I copy the output table directly into the page (static) it sorts. Therefore, I am assuming that the new table is not being added to the Dom and and is not being "recognized" by tablesorter. Does anyone know of a solution to retrieve and display a full html table via ajax and get tablesorter to sort it.
I am getting following data from the server Collapse: < allstudents> < student> < rollno>8001< /rollno> < name>AAAA< /name> < /student> < student> < rollno>8002< /rollno> < name>BBBB< /name> < /student> < /allstudents>
I have html page containing div with id 'dvtbl' now I want to generate the following table inside of dvtbl Collapse < table> < tr> < td>< input type=" checkbox" name=" cbRoll" value=" 8001" id=" cbRoll8001" /> < /td> < td>AAAA< /td> < /tr> < tr> < td>< input type=" checkbox" name=" cbRoll" value=" 8002" id=" cbRoll8002" /> < /td> < td>BBBB< /td> < /tr> < /table> h How do I do it using jquery? In the callback function of $.ajax?
I have a form that submits to a third party WCF service. When the form submits it returns html. Based on that html I need my ajax submit to fire a success function according to the reply. The reply is as such: <HTML><BODY> <TABLE border='1'> <TR><TD><b>Field Name</b></TD> <TD><b>Field Value</b></TD> </TR><TR> <TD>SuccessFlag</TD> <TD>TRUE</TD> </TR><TR> <TD>ResponseMessage</TD> <TD>Service Cancelled</TD> </TR></TABLE></BODY></HTML>
How would I write a success function if the SuccessFlag returns a TRUE in that td? I have tried success: function(data) { var useTD = $(data).find('table').children('tbody tr td:nth(4)'); if (useTD == 1) { $("#request").remove(); $("#requestSuccess").fadeIn("slow"); } else { $("#request").remove(); $("#requestError").fadeIn("slow"); } To no avail. I have also tried using the :contains but I can't get that right either.
Everything works great - the returned value is loaded into .postcontent perfectly. However, a 0 is appended to the end. Every time. Even if I return nothing, a lonely 0 shows up inside .postcontent.
I have a script that uses jQuery to POST data through AJAX to a PHP script, that uses that data to create a dynamic JPG image. The PHP script returns the binary image data as output using the PHP header image/jpeg command (so far so good).
Now I want to display that image in the client, but I haven't been able to find a proper solution for this yet. After reading up a bit I understand a possible solution would be to have the PHP script encode it in base64 and return the string to the client as a data URI. However, that solution won't suffice because it is not supported by IE < 8 and still limited to 32K images in IE 8.
For the moment, I am writing the image to a tmp dir on the server and return a filename to the client. However, there must be another way to solve this more elegantly through. how I can use jQuery/JavaScript to display the returned binary image data in the browser?
I am trying out $.ajax instead of getJSON for debugging purposes. Because getJSON did not report an error in IE (6,7 or 8) and I am trying to figure out why a jQuery plug-in is not painting my returned images to the screen in IE but is in other browsers. So I tried this. Interestingly enough, it hits the error event in IE but not firefox, safari and the rest and I don't know why (this code works great and renders my data just fine in FireFox and the rest). I know my returned json is valid:
I don't know what else to do to troubleshoot why IE is having so much trouble with the returned JSON or just executing the function(data) using either getJSON OR this. I have set the headers not the cache also in the response. IE refuses to enter my function(data) on the response.
Same result. Firefox and the rest had no issue. IE still exited the $.ajax and my error method kicked in. No rhyme or reason whatsoever and I tried the IE Dev tools... nothing. About the only thing I get is this: Line: 163 Error: System error: -1072896658.Line 163 which is simply the line: function() { alert("An error has occurred. try again."); This has got to be the most f*d up situation I've been in and I need to get this working! I just cannot understand why IE can't parse a getJSON or $.ajax response, that is impossible or else there would be a huge meltdown with jQuery.
I have been using a jquery based plug-in, and what i would like to do is degrade it, so a non js enabled browser will hide the relevant div when js is not enabled, and show a different div with appropriate message content.i have followed a couple of tut's which do this on click, but i would like this to occur on page load.
