JavaScript - Replace Characters In Form Fields
Similar TutorialsCan some one help me, I want to replace the characters from a string and I have tried with this script: Code: var v5=form.description.value.replace(/#/, "%23"); But it only changes the first character from the string. Turning #### into %23### but I want them all transformed. This is driving me nuts I need to replace all instances of "zz" with 'Z'. I can easily replace other strings such as a = a.replace(/mickeymouse/, "Z"); but a = a.replace(/zz/, "Z"); doesn't work. Must be a double characer thing? Hi, How can I strip out the dirty characters shown in textarea after to extract the tags from a webpage and before submitting to another page? By dirty characters I take in mind the characters shown in the image below. - Replacing double space with a unique space - Replacing "squares" with a blank space - delete contents between "<!--" and "-->" or "<?" and "?>" Jan Lee Hello I have this snippet for controlling the number of characters entered in a textarea. It works. But, if I replace in this code the name "my_form" by "contact-form" and "my_text" by "message", it doesnt ! It looks like the keyword is " my_form ". You change that , and the script will not work! It turns out that I have to change those names because the form as it was already had those names my_form and message before I added this counter And I dont want to replace the names of the form in order to adapt them to this code snippet below. The question is why would the script not work if I have just replaced two words, which dont seem to be keywords of JS programming (my_form and my_text) <html><head> <title>(Type a title for your page here)</title> <script language=JavaScript> <!-- function check_length(my_form) { maxLen = 50; // max number of characters allowed if (my_form.my_text.value.length >= maxLen) { // Alert message if maximum limit is reached. // If required Alert can be removed. var msg = "You have reached your maximum limit of characters allowed"; alert(msg); // Reached the Maximum length so trim the textarea my_form.my_text.value = my_form.my_text.value.substring(0, maxLen); } else{ // Maximum length not reached so update the value of my_text counter my_form.text_num.value = maxLen - my_form.my_text.value.length;} } //--> </script> </head> <body> <form name=my_form method=post> <textarea onKeyPress=check_length(this.form); onKeyDown=check_length(this.form); name=my_text rows=4 cols=30></textarea> <br> <input size=1 value=50 name=text_num> Characters Left </form> </body> </html> I have been using code such as Code: a=a.replace(/ /g,''); b=b.replace(/;,/g,';'); to eliminate spaces in a string, as well as converting things like ";," to ";" in strings. Several instances of these replacements will have to occur in the strings. Unfortunately, I cannot make it work for converting two commas into one or for eliminating line breaks. Does anyone know how to do this (preferably without using "while")? Hi, I have a working contact form with 3 of the fields requiring validation and they work well. I have added extra fields to the form (StatusClass, Project, CameFrom). These 3 fields return fine but I need to validated them. My problem is that the new fields don't show in the behaviours/validate panel even though they are within the form tag. Can anyone give me any help and advice as to how to accomplish this? Many thanks Code below.... Code: <script type="text/JavaScript">

I am no javascript expert, very much a beginner. I am trying to incorporate some into a web-based form. The problem is the button I created to add extra fields does not work, and I can't find exactly where the problem is. I'm in need of some help from a javascript guru. Help me enjoy my Friday afternoon by solving this! The javascript is mostly borrowed and slightly altered, the "additem" I wrote myself so that is probably where the problem lies! Here is the html: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

Hi I am wondering if it is possible to replace a rating form with some sort of javascript star rating system that would submit the same way? Here is my current form: <form method=post action="%%%SCRIPT_URL%%%"> <input type=hidden name=main value="imageRate"> <input type=hidden name=file value="%%%FILENAME%%%"> <input type=hidden name=category value="%%%DIRECTORY%%%"> <select name=rate size=1> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> <option>10</option> </select> <input type=submit value="Rate This!"> </form> Right now it is a drop down menu and I would like to replace with a php, javascript, or ajax rating script that can keep the same properties. Any advice? Hi guys, This has been asked before, and i've seen many of the previous posts. And tried for hours. But finally i've broken and have to ask for help. What am I doing wrong here? Can someone please explain? Code: var u=document.forms["lead"]["name"].value;
var v=document.forms["lead"]["city"].value;
var x=document.forms["lead"]["country"].value;
var y=document.forms["lead"]["mobile"].value;
var z=document.forms["lead"]["email"].value;
if (u==null || u=="")
{
alert("Please enter your first name.");
return false;
}
if (v==null || v=="")
{
alert("Please enter your city.");
return false;
}
if (isNaN(lead.y.value))
{
alert("bloody work!");
return false;
}
if (x=="Argentina" && y.length < 11)
{
alert("Please enter a valid Argentinian phone number.");
return false;
}
Thanks in advance. Thank you for your reply. With the code I had to acknowledge nothing had been inserted,(that is, still spaces, it was working. When I added the code to only accept alpha chars etc., I inserted numbers, nothing worked, with no error message. Would you, or can I send the whole code through for the form. I noticed that the form tags had been changed so I altered them as well according to your message. i have a html/php form which let users upload pictures onto my server. the problem with it is, it says the picture has been uploaded but if the file name contains any of character apart from text (A-z) and numbers, the picture never shows up in the admin panel. is there a way using ajax or jquery to disallow certain file names in the upload field of the html which uses these characters !@#$%^'&*()"? how do i go on about this? I am wondering if it is possible for me to replace my form submit button with an animated gif (fake progress bar), after the button has been pressed. Having so far disabled the button onclick, I would instead be happy if I could simply change the button text from 'Click here to submit' to 'Processing...' I have done some searches here but I'm finding references to innerHTML, etc., and I'm getting lost now. Is this an easy thing to do? TIA Hi, I am trying to only allow a person to enter alpha characters in this field and if they try to enter a number a pop up box will tell them they can only enter alpha characters. Can this be done? Here is my code: How would you like us to address you? ("Dear Pat" Dear <input name="SALUT" type="text" id="address2" style="color: #000000; border-left: 0px solid #008000; border-right: 0px solid #254D78; border-top: 0px solid #008000; border-bottom: 2px solid #0033CC; background-color: #EBE1BE" tabindex="5" size="15" maxlength="50" onFocus="if(this.value=='SALUT')this.value='';"> Any help would be greatly appreciated. Thanks Hi, i have this code that generate 10 rows with form fields: Code: <form>
<?php for($i=1;$i<=10;$i++) {?>
<div id="rowz-rep">
<div class="row1"><?=$i?></div>
<div class="row2a"><input name="title[]" type="text" class="fieldSubmit"/></div>
<div class="row3a"><input name="url[]" type="text" class="fieldSubmit"/></div>
<div class="row4a"><select name="type[]" class="dropSubmit"><? foreach($allowed_types as $at) { echo '<option value="'.$at.'">'.$at.'</option>'; }?></select></div>
</div>
<? }?>

I need that onclick with JS add 10 more rows so i get something like Code: <?php for($i=1;$i<=20;$i++) {?>

Here's what I have so far in my validation part.

Here's what I have so far: Redacted Hi guys, I created a form that contains about 10 form fields and would like to add the option to dynamically add more sets of those 10 fields if a user clicks a word or a button but I need help. I'm a beginner when it comes to JavaScript and would appreciate any help. This is what I need to generate dynamically. Can someone give me an idea of how to get started please? Code: <div id="dynamicInput"> <ul> <li>1</li> <li><input name='textfield1' type='text' size='10' /></li> <li><select name='commodity' width='100' style='width: 100px'> <option>Option 1</option> </select></li> <li><input name='textfield2' type='text' size='5' /></li> <li><input name='textfield3' type='text' size='10' /></li> <li><input name='textfield4' type='text' size='10' /></li> <li><input name='textfield5' type='text' size='10' /></li> <li><input name='textfield6' type='text' size='5' /></li> <li><input name='textfield7' type='text' size='5' /></li> <li><input name='textfield8' type='text' size='5' /></li> </ul> </div> I have two slightly different forms on the same page, but I want the values in form1 to auto populate the same form fields in form2. 1 field is a text field, the rest are drop down menus. How would I accomplish this? Link to tutorial would be much appreciated. Thanks
Several posts here are almost what I need, but I can't put it all together.... thank you for your help, this is for a pet rescue charity! When selecting "mini" option, my form should should only allow typing in 6 out of 10 text input fields (the first 3 on the front, and the first 3 on the back too if its selected). Other sizes would allow typing in all 10. The NAME must be the same due to the shoppingcart used, but ID can be different. Also, if mini the maxlength of each should be 14, other sizes each maxlength is different. I will try to put the relevant code below, but one entire form is he http://wooftags.com/bone-iframe.html Code: <select name="product1[]">
<option value="mini">mini</option>
<option value="small">small</option>
<option value="medium">medium</option>

<input type="text" name="product1[]2" size="14" maxlength="14" style='text-transform: uppercase;' onblur="this.value=this.value.toUpperCase()" />

I'm trying to make a site where when you click the submit button it puts an asterisk next to all of the incomplete fields while also displaying an alert box. I'm having no luck with it so far since I don't know how to get a script to print something to a specific part of a page. Here is what the whole thing looks like so far. I tried using page-jumping but that didn't work: Code: <html>
<head>
<title>Sortomatic 5000 </title>
<script type="text/javascript">
function Sort(form){
var fruits = [form.One.value, form.Two.value, form.Three.value];
if (form.One.value!=""&&form.Two.value!=""&&form.Three.value!=""){
document.writeln(fruits.sort());
}
if(form.One.value=""){
alert("Please enter at least one character into all fields.");
parent.location='#first';
document.writeln("*");
}
if(form.Two.value=""){
alert("Please enter at least one character into all fields.");
}
else{
alert("Please enter at least one character into all fields.");
}
}
</script>
</head>
<body>
<form name="Sortform" >
<input type="text" name="One"><A NAME="first"></A><br>
<input type="text" name="Two"><br><A NAME="second"></A>
<input type="text" name="Three"><br><A NAME="third"></A>
<input type="submit" onClick="Sort(this.form)">
</form>
</body>
</html>
