Ajax :: Response Text Prefixing And Suffixing White Space?
Jul 15, 2010
I am learning JS and ajax.. successfully writing my own working scripts.. but, being a newbie, still hit the wall alot. Today's wall really has me stumped:
Developing locally, I am calling a page with a working XMLHttpRequest object.. and getting the response, fine. The problem is that the response is coming back with some space chars tacked on. There are like 10-12 space chars prefixed, and one space char suffixed to my response text. Even if I just stick in a single "a" char in the (now static) page that I call, it still returns
I am creating a class for all of my code snippets, using a formatted paragraph (and "word-wrap: pre") to keep formayting intact. The problem is that in keeping my HTML files formatted nicely, they are indented, and due to the "pre" formatting the indentation is kept. Code:
Right now when someone clicks on my listbox I immediately do an update on the form to populate the selected item.
Is there a way to detect if a user has clicked on some white area of a list box? If my list is sized 8 items but the list only has 4 items, if the user clicks near the bottom of the list where there is no item to select, can I detect that? Currently I get the form updating even if I click on the white area of the list and I'd like the form to update only if I actually click on an item in the list.
I have a frame that includes a hidden <div> at first (before any action), the problem is that when opening the page, I have a white space, and i can't reduce the size of the frame because the content of the <div> will not appear!
how to hide the white space of the frame without reducing it's size?
When addClass('choose') to li, there is always a white space right under it. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URl]"> <html xmlns="[URL]"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <script type="text/javascript" src="demo_inc/jQuery.js"></script> .....
I'm thinking of putting a pop-up on one of my sites using the following javascript. I only want it to pop-up when a visitor visits every 25 days or so. Can someone tell me where I put the code for that in the below script or point to a script where this is already done? Code:
I am trying to adapt the form validation script at [URL] to a site that already has tons of pages with forms. Unfortunately, the forms include selection lists that often have SELECT names with white spaces included, and these do not work when passed as a variable to the frmvalidator function
The site I want to use the script on is being database generated and has something like 25,000 item pages, each with several SELECT list options. The Option variable uploaded to the database looks like:
Code:
"Optional Out Going Mail Slot" "Choose" "None, " "Add Mailslot in Top Left (Item # na) (+$15.00)" "Add Mailslot in Top Right (Item # na) (+$15.00)" "Add Mailslot in Bottom Left (Item # na) (+$15.00)" "Add Mailslot in Bottom Right (Item # na) (+$15.00)"so it would be a serious task to download the database, loop through and replace white-space characters with dashes or underscores on the first element in each option sequence. Is there some way to make names with white spaces work? I could switch to a script that simply checks all selection lists to make sure that option 0 is not selected. But I love all the other features of name, format and combined verification in the above script. Unfortunately, the script relies on the name and validation action of each form element being passed to its function onSubmit.
Ok so the problem is when I mouse over the left nav menu all is great, when I mouse over the newly created DHTML menu in the middle the seperators(black before mouse over of the DHTML menu) disapear on the left nav menu and there is now white space surrounding the buttons on the left nave menu. IF you switch to full screen mode(F11 I think) I can see the actual graphic on the left nav menu changing and that is what is causing this, but I cant find it in the code.
I have narrowed it down to my framework.js script but no idea where it is within this code. I can post that code in here and maybe you can see what I mean and I will attach a screen shot of the problem.
i am using the following regular expression for the validation of Email address /^.+@([?)[a-zA-Z0-9-.]+.([a-zA-Z]{2,3}|[0-9]{1,3})(]?)$/; but the problem is that if user enters any white space character while entering email address then email is considered as valid how ever we know that an email address can not contain any white space character i have tried a lot but could not get a correct regular expression
i have wriiten a form in my php page and i did call an ajax function on onsubmit, based on my ajax response my form have to be submit...but i am not getting ajax response text some times. But some times i got it correctly..i have used post method in my ajax function.
formid="reserve"; var f = document.getElementById(formid); var keyValue = ""; keyValue = buildKeyValueSearchFunction(f, keyValue); alert(keyValue); ajax_request = createRequestObject(); [Code]...
I have some pages being loaded via ajax and I want some of the elements hidden when the page is loaded.I could hide them with CSS and then change the css attribute when I want them to show but that just seems clunky to me since I'd have to assign <input style="visibility: hidden;"> to everything I wanted hidden on load. I know how to make it visible later when I need it.Using jquery's document.read doesn't seem like a good solution either since I'd have to make a list of everything I might want hidden right there on the main page.
I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function:
function show_video1(){ document.getElementById('video1').style.display="block"; var video1Name = "Education World News (Part 1)"; document.getElementById('video2').style.display="none"; document.getElementById('video3').style.display="none"; document.getElementById('video4').style.display="none"; [Code]...
and trying to call it later on with this: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name.
I have an ajax post which returns a large html response. It is getting truncated at 98784 characters everytime. Is there a limit to a response size or a way around this?
I'm having trouble getting FireFox 2 to play nicely with a jQuery fade. Here's a paired-down example:[URL]..I've made the source code VERY basic here to make it clear what's what. When you click the link, some jQuery fades the image in and out. But it also makes all the text go thinner. Clicking away from the link then sets the text back to how it was.
Any ideas why this could be? I've googled it and although I can find people with issues around jQuery's fades, I can't seem to find a solution to this one.
I want to dynamically resize textareas to always have enough rows to hold the data, so there is never a need for a vertical scroll bar no matter whether the user types in large paragraphs or only puts one character per line. Is there some kind of existing facility for doing this? Perhaps in a library? Or maybe there is a property of the textarea which can be checked in a row-incrementing loop to determine whether a scrollbar is still needed.
Some servers return JavaScript as the response to an AJAX request. When the response JavaScript is eval'ed it calls other JavaScript functions already in the browser to update elements, etc. This seems like a good system because it allows so much freedom in creating the desired behavior in the browser. The required data doesn't have to be converted to XML or JSON on the server. The browser doesn't have to have templates for interpreting and converting this data into some change in the browser. All of the conversion algorithms don't have to be written and changed when new behavior is required. This remote procedure call approach is the predominant system in the Ruby on Rails world. (Unfortunately they are calling Prototype.js functions.)
However apparently some people seem to think this remote procedure call approach is a bad idea. I can't see why it is so bad because it is so lightweight and flexible. It also helps to keep the client less intellegent which seems good in a world of incompatible client-side bugs.
If I use some neutral data format like XML to accomdate different types of clients then I have to write different client-side interpreters for each type of client (browser, RSS, POP, cell phone, etc). Why not just write different server-side code that generates the correct JavaScript (or other) for the requesting client type?
I am using ajax / php where I am looking up some info from the database and populating a select list dynamically, however I am running into some sort of size limitation with the ajax.response object. If the string I am passing to javascript from php is too large javascript does not get it all the data. The magic number appears to be 6123 characters, anything below that it works fine, anything above and if I alert the ajax.response, I see the string is cutoff. Any ideas where this limitation is defined?
Now what i want to do is: i have a callajax() function. with in this function i will call do_login() function. this do_login() handles an ajaxrequest and returns the responsetext.
Now i want to do some validation on this responsetext(in case of onsuccess). so i am trying to return value to callajax() function for onSuccess case in ajaxrequest.submit();
That is(onsuccess response) supposed to be some string( but not true or false). but i am always getting false in ajaxcall() function. i know the do_login() function is returning false before ajaxrequest completes
So i want to stop this and make do_login wait until ajaxrequest completes and then i want to return it's response to callajax() function.
I am wondering how possible it is to use eval() to parse javascrpt that is pulled in through ajax(innerHTML)? I have found a few notes about this, such as:
