determine what the first letter of a selector is? For example, if the very first letter of a paragraph is a quote (or a ‘ , or a “ , etc) I would like to apply a negative text- indent to the found paragraph so as to replicate "hanging quotes" that are commonplace in the print world. The code I've come up with is: $("p:contains(“), h1:contains(“), h2:contains(“)").css({'text- indent':'-0.3em'}); but this grabs any p or h1 or h2 that *contains* an opening curly quote; not what I'm looking for. I need it to select paragraphs that *start* with the opening curly quote. Incidentally, I could not get this to work when I was searching for $ ("p:contains(“)... but it worked when I entered an actual opening curly quote in the search (as above top). I tried both single and double escapes too.
I have a HTML form which takes some values including a password field. I have a JS function to check and alert when a user enters some particular special characters(this is bcoz only these characters are not allowed in the back end of the html form, all the other special characters are allowed). following is the code for it.
function checklen() { var iChars = "`<>"; for (var i = 0; i < document.ipform.password.value.length; i++) {
[Code]...
now i want a feature which does'nt allow the user to enter an uppercase letter or a special character(only these are allowed~@#$%^&*()-_+|) as the the first character of the password field. Since i am newbie to JS, It would be a great help if some one can help me to sort out this..
In my application (yes I know that it's asp) I need to automatically replace a character if it is found in the textbox Is there a way to do this. this is how it renders on the page
This is all triggered from a, input :select. If a specific option is selected, generate a text field to enter a reason. the generated input carries an id: txComments_01/01 (this being the value pulled from the attribute "data-date".
The client only wants one per week, so if it exists already don't re-create it
So, I would like to be able to have people click on a link, and the an input field with a file will open. But I need to see if the browser has support for it. Chrome and Safari support this. Firefox 3.6 does not, but Firefox 4 does. The "right" way for this is normally feature detection, but I have no clue how to test for it in this case. Is it possible without user agent sniffing? Say I create have an input element that I can reference via a variable "uploader", things that do not work: testing !uploader.click seeing if uploader.click() throws an exception It seems you can call click on the input field of type file, but nothing happens in many browsers. If you'd like to see what I mean. You can play with code at my page.
I have a script that is supposed to: Make sure that the user selects a performance from a select field Make sure that the user hasn't selected a performance that contains the string "SOLD OUT" in its value Here is the code I am using:
I'm pretty new to jQuery and I'm using $.getJSON to submit some data to a PHP script which either returns 5 sets of json-formatted data or data to indicate an error condition (i.e., no data available) from the PHP database query. The callback routine handles the 5 sets of json-formatted data just fine (using $.each...) but I'm having trouble testing for either just a string with 'null' in it or a json-formatted data return of [{"error":"null"}].
My callback code for the second approach looks like this: function handle_stores(data) { if (data.error == "null") ..... But this test does not execute the following code for the 'true' condition, i.e., data.error == "null" never evaluates to 'true'.
Is there any way to test for the presence of the Adobe Acrobat plug-in in Internet Explorer? It's doable in Netscape but so far I cannot get it to work in MSIE.
I'm trying to get JSUnit to work - I've tried everything I can think of, but I can't get the simplest of tests working - example 1 of the jsunit homepage - Both on my server and locally, nothing happens after clicking run - or if I'm lucky, a window pops up, blank, other than the heading "Tracing - JSUnit".
I had a rethink about my problem discussed in this [URL] thread, where the function won't run properly a second time if the page hasn't been reloaded. That one appears not to have a solution, and I was thinking that a reasonable plan B is the following:
a) test if the function has already been run since the page was loaded
b) if not, run the function
c) if it has, reload the page with the onClick, then run the function automatically on reloading.
the problem I envisage is will the page "remember" to run the function once it has been reloaded?Of course, it would be simpler to do it running the function automatically once the page loads, then just reloading if the test comes back that the function has been run already, but that wouldn't work for the first time you visit the page - it would start running straight away, whereas I want it to wait for that first click. Here's the page [URL] I'm working on, if you want to have a look.
I was putting some javascript in a form and doing my usual testing and swearing when the javascript did not run without an error message of any type and reverting the code back until it did run and adding code til it didn't.
Then it hit me - isn't there a better way - doesn't someone have a program or utility that will help debug Javascript ???
As I'm doing Javascript it is much harder to decode than the 30 year-old Fortran programs - they typically gave a line number and variable name that was missing.
When I did Basic before Visual Basic, the editor identified errors in real time as we typed. What is available for Javascript?
If I have to test my code on different Netscape versions, can I download and run those versions on the same computer or will it create conflicts? And if I had to test only one version which one should it be - which one has the most common elements to all the versions?
I am trying to check if my new window is open and if it is change the url. This works until I use the x in the corner to close the window. At that point i get an error when i try to open the window again. I believe that it is because newWindow is still active. How do I close newWindow when it is unloaded or closed by the x. If this is truely the problem.
does anyone know how I can test, in javascript, which of several buttons was pressed when submitting a form? Currently, I use the onSubmit event handler to call a form validator function, and it is in that function which I would like to test which submit button was pressed. Anyone know?
Is there any way to test if there is overflow in a text area (i.e. a scrollbar is displayed)? This is a read only field so I could change the textarea to a div if necessary.
Is there any way to detect through Javascript whether a browser supports a particular property of CSS? I am experimenting around with CSS3 and I would like to be able to detect whether the browser understands what to do with a particular setting, as in "elementRef.style.newCSS3_property = '3px' " I have heard, although I do not know if its true, that there is some way to access whether the browser knows what such a declaration means.
Code: <script language="javascript"> <!-- // Max number of items to show/hide
[Code].....
Which is designed to hide all but one of a group of DIVs with consecutive IDs in the form "listings_stations_<number>". The problem is, I won't know how many of these DIVS there will be. I know a maximum possible number though.
The script as-is works, but obviously throws up errors trying to get handles to non-existent elements/objects. How can I check an element exists before getting and setting style properties for it? I'd like a solution that works for all three browser-types the script currently works with.
I'm trying to check for this bug with the following script and it *seems* to work. In IE it reports "bubbling" and in Firefox "not bubbling" but I really have no direct way to confirm the Firefox results until the bubbling bug is fixed.
Basically the test script assigns an onscroll event handler to a textarea and then scrolls the textarea down then back up, checking to see if a the event handler works (assigns the "bubbling" variable a "true").
I had to code things with a few settimeouts otherwise Firefox, unlike IE, wouldn't display the down then back up scrolling of the textarea. Which may have been a problem.
Lacking a "debugged" Firefox browser, is there some further (indirect?) tests and/or rational that would support or discredit this script as a valid onscroll event check? ....
So firstly this is likely not in the right place at all, as it's a bit OT but I figured it's the best place to ask. I have to document 4 different tests to my code; what structure should I take when doing this?
I was thinking:
* State the aim of the test
* State the inputs, and what I believe the output should be.
* State the actual output, and whether this positively or negatively affect my code.
