Dynamic TextArea Text Setting Workaround With Newlines
Jun 4, 2009
I dynamically make a textarea and save the text, but when I try to output it with javascript, the newlines screw it up... if you don't understand what i mean, here is some code:
Code:
With that newline in javascript, the javascript throws an error. i am working in jsp, so how would i change the text that is put into the textarea with javascript without changing the newlines?
I've written this javascript that puts lines of text into a readonly textarea, each line ends with a newline character. I have a function that checks that no duplicates exist, it does this by splitting the textarea by newlines into an array. This works as it should in Firefox, but not in IE. Code:
I am very new to jquery and I am trying to set the value of a textarea which is not in a form, into a hidden field which is in a form. In the text area, I have given it an id called refnote and ive used the text() to get the text in it. However, the problem is setting the retrieved text in a hidden form field. $('form').submit(function(){ alert ($('#refnotes').text()); return false; });
I have found a script that works fine for me but I'd like to make it reusable but I have an issue with that. On the script I have something like
function my_function() { var $container = $('#panel .container'); } and I'd like to pass the id (panel in this case) as a parameter like in the example below:
PHP has a function called nl2br() which takes all the newlines in a string and turns them into break tags <br>. I need to do the same in javascript. Is this about right? I'm not sure how one is supposed to reference invisible characters in Javascript strings. I took an example on the web and tried to modify it to my uses.
function nl2br_js(myString) { var regX = / /gi ;
s = new String(myString); s = s.replace(regX, "<br /> "); return s; }
After looking around quite a bit using Google, I still couldn't find out what the gi in the above example is for. What is it?
I have some Javascript code that reads and sometimes sets the content of a textarea. I want this to be reasonably browser and platform independent. My question is, what characters should I expect to find at the end of a line? I suspect that I need to cope with either "" or""; can someone confirm?
Setting the content is more of a challenge. I don't want to have nasty browser detection to select what to use for newlines. Is there one newline pattern that is safe for all browsers?
Is there either a client-side solution in HTML or Javascript, or will I have to use a server-side solution in PHP? I'm completely stuck and under a Monday AM deadline to come up with a solution.
I am trying to code a webpage that does the following:Listens for user key presses in an input box and dynamically writes them below the input box in a textarea.
I'm trying to write a script with two standard drop down boxes. One contains days one contains the month. I want to update the options in the days box everytime the month is changed... i.e select August, and days are filled up to 31, select September and only 30. The part where I am having difficulty is that after the onChange event has triggered and I have checked what the new month is, filling the box with relevant values is tricky. Code:
I am using the cluetip plugin to show a formatted version of text thatthe user types into a text area. So I have a <textareaid="description">, and as the user types, they can at any time click a"preview" button will call cluetip to display the popup. Here is mycurrent cluetip call:
I have a content slider called "Codaslider" (ver 1.1 I believe) setup, and using CSS I have an absolute positioned image hovering above the slider at all times. The effect is what I want, where I have a static image of my company's product hovering above the content slider, and the background images slide around showing various features and such.
I would like to make it where the customer can click anywhere within the bounds of the content slider (including on top of the static image), and be able to follow the link for the image in the content slider.
For example, if the background image shows "New Features" or something similar, I want the customer to be able to click anywhere and get to the "New Features" page.
So basically, is there a way to dynamically set the URL that the static overlaid image points to, based on what page the content slider is on?
Here is the javascript that setups up the content slider:
Code javascript: <script type="text/javascript"> var theInt = null; var $crosslink, $navthumb;
I would like to restrict Character limit on TEXTAREA box.I am able to get char limit using Jquery if it it is one textArea. limit chars for Multiple TEXTAREA in same page using jQuery Code.
<script type="text/javascript"> $(document).ready(function() { // ---- How can I do on keyup $('textarea
I am creating a small CMS module for a client. I created a little form and when they click Submit, it goes straight out into an include (.inc) file, which is connected to the web page to be displayed.
The trouble I am having is that I'd like to create an additional button that will insert some text (certain html tags to make their life easier, etc) - I got it to work, actually. The script executes and the text is inserted - but once the script runs and the page refreshes (or whatever it does), the text then disappears. The only way I can seem to get it to stay put is when I use "onmouseup" instead of "onclick" - which means that every time the user accidentally mouses over the thing, it inserts the text.
we probably all know the problem that select boxes under IE are always overlap DIV layers. Afaik there are two workarounds:
1. hiding the select box 2. IFrame beneath the DIV layer
But I don't know how to do that.
We want to show a DIV layer as tooltip. The DIV layer has no defined size (neither a width nor a height attribute). The size depends on the text the user defined for the tooltip.
My questions:
1. How can I know when the tooltip is 'over' a select box, so I can hide it.
2. How can I define an IFrame that has the same size as the tooltip, when I don't know the tooltip's size?
This bit isn't mine, I found it. You normally have to use this by copying it and then pasting it into the address bar when you are on the "Select Friends" screen.
I'm currently constructing a javascript "terminal" on a site I'm building so that I can test objects and functions outside of the web developer terminal in google chrome.
Given that I have active javascript defining an object called item, typing item in the chrome terminal returns Object and goes on to list the properties of item.
Moreover, I can define a function in the terminal like this: function(x) { return x }, and then function(item) will return Object and list the properties. However, if I use form data and user input in the place of the argument, the datatype becomes a string and not an object, so typing item in the form and clicking a button that performs function(document.form.text.value) returns the string item and not Object.
Is there any way to convert this primitive string to an object so that I can then iterate through properties, and so on?
If you click the link on [URL].. a form pops up. How do I set the value of the URL text field in the form to be equal to the url of the page it originated for i.e in this instance it the value would be[URL]... i believe would set the value to the current url. What I need is the value of the url the pop up originated from.
I have developed a widget. I am using the jquery core api. Im having a problem when the widget is used in a weebly site. I know weebly uses prototype and I am using the workaround:
var $j = jQuery.noConflict(); however there is still a clash of some sort. I think every prototype.js function is being called or something because the page is taking a long long time to load as there are many requests being made which look like this:
I was having trouble getting the object.focus() method in IE and in FF working, so came up with this workaround.
What I wanted to do was check if a textfield was numeric, if not, inform the user then select the text and set the focus back to the field.
Sound simple? object.focus() simply doesn't work in firefox or (I've been informed) IE.
Solution:
Instead of checking when the field losing focus (onblur), check when the next field receives focus (onfocus). Then call a function that gets the element index of the object, and use that index to check the element above it. Difficult to explain.
Here it is...for the textfield you want to check, put this into the next form object after it onfocus="checkNum(this)"
then put this script in the header section...
function checkNum(obj){ var idx; //get object index for(idx=0;idx<document.forms[0].elements.length;idx++){ if(document.forms[0].elements[idx].name==obj.name){ break; }; }; //check for numeric if (isNaN(document.forms[0].elements[idx-1].value)){ alert('Value must be a number!');
Am creating a dynamic text box along with datepicker image.. when I enter newdate into the text box, it simply goes to previous textbox and updating the textfield. How to enter the date into the newly created text box??? And also once I complete the first row data , that row should be disabled.
