JQuery :: If Text Area Contains Certain Character, Trigger Alert?
Jun 30, 2011
I am creating an application where users can type a message into a text area. I want it so that when they type the character "@" then an alert is triggered. My textarea is #usermsg. At the moment I have the following but I think I could be barking up the total wrong tree with it.
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..
I use fckeditor at my form for a text area. I want to change te value for this text area with the onchange "trigger" of a select box.How I can do that? I used things like that but does not work
There is a Text Area that user can enter text. assume that user enter something and put a dot Following values should be populate in a drop down at the place where dot locate .
like when we get the string object using Net Beans IDE and when we put "Object." , drop down will be displayed with available methods for that particular object. idea is to build a editor using java script.
I've got a text input field to which I've added some autocomplete functionality using jQuery and AJAX. The function which loads the autocomplete script is currently triggered every time a key is pressed, but I want to refine this so that the only keystrokes which trigger the search are alphabetic ones.The reason I want to do this is that pressing, for example, backspace, still triggers the autocomplete which I don't want.My current code looks like this:
Code javascript:
$("#searchbox").keyup(function() { var inputbox = $(this); var keyword = inputbox.val();
Can't get this to work correctly. I need to run an alert if the user clicks the button "#step0Next" and none of the var ckd button's are checked [code]...
I am currently doing a fadein and fadeout function using jquery. When I click on a <a>, the page will fade in. There is an alert message (which is the javascript alert()) prompt out on the page once the page fade in. However, I want to fade out the page when I click the "OK" in the alert message.
I've tried but cannot success..
$('alert').click( function(){ $('#fade , .popup_block').fadeOut(function() { $('#fade, a.close').remove(); //fade them both out
1. When I have the "<textarea>" code lines in it put a text-area on the page, but it puts all of the code following that first text-area line into the text-area box and doesn't execute that segment of code.
2. When there is no "<textarea>" (for the sake of seeing if the rest of it worked) it doesn't check the survey.
I'm stumped and can't figure out what to do at this point Code and pictures follow:
I've been following this tutorial (and it works great)URL...Just cannot figure out how to make one of the Text Fields a Text Area with cols="45" rows="5".Every combination I've tried turns off the validation. I've already added completely different text fields from what are shown in the tutorial so I know how to change up the javascript I just can't get the Text Area right.
<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">Hello, I would like to know if I can load a small text from a external source into a textarea. the external source is a php that will write some clean text depending on the vars received. I know load() can do the job for a div but I don't think it will work for a textarea. </td></tr></table>
Couldn't find it in documentation.For example i have <span>text</span> and when someone clicks on it, itshould trigger checkbox to "checked" or "unchecked".
I want to get the cursor start and end position of a selected range in a text-field or text-area. i tried lot of functions in various forums. but when the last character of the selection is a new line character JavaScript ignore it in IE6. any one having idea ?
I have a form setup so that selecting a radio button opens a specific text field. The problem is if the user starts to enter information, then switches to a different radio button (perhaps they chose the wrong radio to start), the text they already started to enter on the previous textfield doesn't get cleared. This will be a problem later when inserting to sql.
As of right now I have a code that will work in IE but wont work in FireFox...go figure. Basically what I want to have happen is when you type in an area code it will provide an output in a predetermined area of the page.
For Example: Input- 512 Output - Austin, TX
The code that I have doesn't work with firefox and I was just wondering if there was a code that would allow that to happen.
Would u pls let me know whether the following is possible or not: User can be able to insert text on a text-box or text-area(form) as usually we use text-area to do so. But I want to put some readonly text using an open and close tag
for example: <ro>This is readonly text</ro>insert your text here Can I be able to make the text inside <ro>..</ro> tag readonly, it means user can't be able to modify or delete this readonly text. readonly text length not fixed. only way to recognize the readonly text is the <ro> tag.
I'm using jquery-1.4.2 with PHP. I have a grid of records with a link to a form i'd like to use to edit the row with. The form is built using php, and works as expected when called just using a regular html link.
When the form is called using $(".ajax").click(function(event), the form comes up, but the textarea(s) are messed up; <textarea>Stuff for the text area
im clueless when it comes to javascript, but this is what im trying to find: i have a page that has multiple text areas, i also have 4 links that when clicked i want to add some predefined text into the active text area the one with the text cursor in?
I'm trying to 'wrap tags' around text in a text box.
<script language=javascript> function insertFauxTags(fauxTag, e, endFauxTag) { var e = document.frmAddNewForum.txtTopicMessage.selected; document.frmAddNewForum.txtTopicMessage.Value += fauxTag + e + endFauxTag; } </script>
<a href="javascript:insertFauxTags('[p]' + e + '[/p]')"><img src="http://www.<%=strSiteName%>/images/parabutton.gif" border="0" alt="Paragraph" /></a> When I run this in FF I get 'e' is not defined - any ideas?
I have the user entering into a text area box but as they are typing into the text area I want it to replicate the first 250 charactors into an input (text) box.
