JavaScript - Cannot Create Textarea Using Javascript
Hello,
I'm trying to create a textarea using Javascript, the function creates a textarea in IE, but it does not create that element in Firefox and chrome. JavaScript Code:- Code: function addRow()
{
alert("function start");
var table = document.getElementById('tableId');
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var cell1 = row.insertCell(0);
var textNode = document.createTextNode(rowCount + 1);
cell1.appendChild(textNode);
var cell2 = row.insertCell(1);
var textArea = zxcFormField('TEXTAREA','option1');
textArea.setAttribute("cols","20");
textArea.style.height = "42px";
textArea.style.width = "496px";
cell2.appendChild(textArea);
alert("function end");
}
function zxcFormField(tag,nme,type){
alert("2 function start");
var el;
try {
alert("In Try");
el=document.createElement('<'+tag+(type?' type='+type:'')+' name='+nme+' >');
}
catch (e){
alert("In Catch");
el=document.createElement(tag);
if (type) el.type=type;
el.name=nme;
}
return el;
}
When I call this function it goes in the catch block in Firefox and Chrome, the textarea is displayed and it disappears with a flash. I've banged my head against wall trying to figure this out. Thanks, Abhishek Similar Tutorialshi i am new to javascript. i want to make a form where a textarea, some buttons like bold,italic,link etc will be availablw. when user selecet some text from textarea and click bold button then one openig and closing tag will be added like this [sb]abc[/sb] how can i do this using javascript. any idea? pls. help I am looking for a javascript that when a image is clicked on it clears a textarea
Hi I'm looking for ways to limit the textarea input, I dont want people to enter hundreds of lines cause, i only want them to enter max. 10 lines. I've looked at several javascripts (cause the problem only can be solved by javascript), and came up with this script: http://javascript.internet.com/forms...-textarea.html . It works great and even has a counter how many characters are left to type in. However when I copy paste something, the 'counter' doesnt adjust right away...it does when I try to type in something extra though. Is it possible to make the counter adjust automaticly whenever there is pasted ? I guess you guys have to test to see what I mean. Thanks in advance !! I'm not 100% sure if this can be done (I haven't been particularly successful in my Google searches). I'm using Javascript and forms to create conditional information randomizers for data. An example might be "What should you have to eat?" The person can generate a random result or select restrictions (selecting an allergy to X would eliminate X-related results). I prefer to work with black backgrounds. Even if I end up changing a default site layout to non-black (for audience purposes), I'd want a personalized CSS for myself. I'm running into some difficulty determining how to make my textarea black. Is there a way to apply CSS to textarea boxes (including those related to javascript?) Ideally, I'd like to be able to automatically style every textarea but if that is not possible in relation to javascript, I'd settle for changing the code for individual boxes. I was unsure where to place this topic so feel free to move it if it's better suited for CSS. Thanks *** I figured I didn't need to bump my post needlessly, but Thanks to "devnull69" as the provided solution worked. For some reason, I was confused about how to type that operation in css properly. That's probably one of the problems that arises when one combines staying up late with learning multiple programming languages at the same time. All is well now. I found and am using the following script to add checkbox values to a textarea. Code: <script type="text/javascript">
function add_sub(el){
if (el.checked)
el.form.elements['type'].value+=el.value;
else{
var re=new RegExp('(.*)'+el.value+'(.*)$');
el.form.elements['type'].value=el.form.elements['type'].value.replace(re,'$1$2');
}
}
</script>
</head>
<body>
<form name="form1" method=post>
<textarea name="type" rows="5" cols="35" onclick="this.focus();this.select();">
</textarea><br>
<input type="checkbox" name="bob" id="bob" value="<p>" onclick="add_sub(this);"><label for="bob"><p></label><br>
<input type="checkbox" name="bob1" id="bob1" value="<span>" onclick="add_sub(this);"><label for="bob1"><span></label><br>
<input type="checkbox" name="bob2" id="bob2" value="<div>" onclick="add_sub(this);"><label for="bob2"><div></label>
That is working. However, I wanted to put carriage returns after each checkbox value added, so I added the + "\r\n" as follows: Code: <script type="text/javascript">
function add_sub(el){
if (el.checked)
el.form.elements['type'].value+=el.value + "\r\n";
else{
var re=new RegExp('(.*)'+el.value+'(.*)$');
el.form.elements['type'].value=el.form.elements['type'].value.replace(re,'$1$2');
}
}
</script>
That is working when adding the value, but removing the value when the checkbox is unchecked is not working. I know the regular expression, etc. needs to be updated to account for the carriage returns, but I have tried everything I can think of and cannot get it to work. Help correcting the code is appreciated. I am trying to create a sample form using javascript. The form has a series of option and a submit button followed by a textarea. When the user clicks the submit button the textarea should be filled with the selected information from the form. I cannot get the textarea to fill with text. I believe the problem lies in the fact that when I submit the form the page refreshes, but I am not sure if that's the case. With this version of the code I actually can't get passed the Room Type. It always says No Room Type selected. Here is my code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

And here is a link to the page: Form Sample I've done a bit of searching and I can't find the answer to my question. I'm working on a website for my business. I have some basic knowledge of coding but I'm mostly a code cobbler. I find various pieces and put it together and hope it works so take it easy on me. I have some code to display products on my site. It works fine. We just have a lot of products and for me to add each one by hand was getting ridiculous. I finally had the bright idea to use Javascript to generate the code for me and then copy it back into my actual HTML page. Last night I wrote the code below. It works perfectly except I have to constantly "View Source" in order to get the code. I was hoping to cut down on a step or two and have the code go into a TextArea. From there I can just select it and copy it into the HTML file. It should make things a little quicker and most importantly easier. Maybe after that I'll try to figure out how to write function to select everything in the TextArea and copy it to my clipboard. That would make things even faster. Any help?

Hi i need to use an equivalent of the php function array_count_values() Any help with that please cheers ewire I need to create an interactive map similar to the one on this site: http://viewers-guide.hbo.com/game-of-thrones/#!/map/ It is a map of a fictional area ( a real area but there are fictional buildings and characters on it) so I don't think google maps plugins are suitable. I don't want to reinvent the wheel, so if anybody has a good suggestion of a good jquery/javascript solution for interactive maps, please refer me to the relevant information. In other words, I need a map where by clicking the objects on the map, a popup window pops up with additional information about the 'scene' or a 'character'. In addition, the map will be dark from the beginning and more and more sites and characters will be revealed on it every week. Thanks for any tips! I'm writing a script in javascript(actually a chrome extension) and I need an object that I can write to it like this(sorry, don't know how to explain it better) and then I convert it to string with format of json. Code: id[129].weekDay[6].hour[23] = 0 Here, id is an array, that each element in it contain another array(weeksDay) and in that array each contain another array(hour). The id indices are unlimited, for weekDay 7 and hour 24. I searched in google but i couldn't find what I wanted. Actually don't know the best keyword to search.(objects in arrays?) I don't know what exactly it is called, I can write it's declaration in VB.NET if that helps you. Hi i have an requirement i.e., i need to allow user to select one of color from color pallet and i need to store that color code value in database, how can i do this I am using jsp and js and html . I know I can use the functions like parseFromString() to access and modify an existing XML documents, but is it possible to use JavaScript to create a blank xml document? I want to take data entered into the client, package it up as XML and use ajax to transmit it to the server. So far I've written my own class to create a simple xml document, but I'd like to do it properly with the inbuilt functions. Hi, I am in need of creating a image toolbox in a web browser using javascript. Please find the requirements below. 1) The toolbox will contain some images within it. The toolbox can be moved anywhere within the window. 2) It is possible to drag and drop a image clone from the toolbox to the window. 3) It should be possible to click on the image in the toolbox and can be placed when click on the window (at the clicked position). 4) on double clicking the image in the toolbox, the selected image should get cleared. Please provide suggestion as well as the code snippets to achieve the requirements. Kindly reply ASAP. Thanks, Vinoth.K Hi everyone, i am stuck at a problem. i am trying to craete a redimmensionable array using javascript, is there a way to do this, i know that this can be done in vbscript using redim and preserve commands. If not then is it possible to variables between javascript and vbscript, or call vbscript function using javascript. a sample code will be much aprreciated thanks for your time! J I have called a table through XML with four fields. One of them is Excel file name. I like to make a clickable link with Excel file name to open it.
