JavaScript - How Does The [php] Tags Work Here In Codingforums
I was wondering how somebody might be able to do the recognizing text between the php tags and making it into colored text in its own colored area like codingforums has done.
Similar TutorialsI'm very new to javascript & would really appreciate any tips or help you guys could give me. Bascially, I have a form which I need to check if certain inputs are empty and send an alert... I also want to be able to send a client-side alert if the formatting of the email is wrong (it's not a valid email). I really don't want to use a jquery plugin or overcomplicate the code. At the moment I'm using the following code (which checks inputs are there) & was hoping someone could explain how I could add the email validation into this: Code: function checkform ( form )
{
if (form.name.value == "") {
alert( "Please add your name." );
form.name.focus();
return false ;
}
if (form.email.value == "") {
alert( "Please enter your email address." );
form.email.focus();
return false ;
}
return true ;
}
Thanks in advance guys & i look forward to contributing on here in future . Also, if anyone has some good places for me to learn javascript, that too would be awesome! I've got this listbox full of hundreds of employee names. Clicking on a name executes a function using onchange. Because of the length of the list I decided a search function would be really handy and I finally found one that works. Now the search function, when you type in the input box, scrolls the list to the first matching entry. And that's good, that's what I wanted. The problem comes in when you try to click on the name the search function found. Nothing happens ofcourse because the onchange tag in the list reacts to changes, not direct clicks. <select onchange="display.apply(this, this.value.split(','))" multiple="multiple" id="People" name="People" style="border-style: none; height:260px; width:220px; margin-bottom: 15px;"> <option selected="selected">Loading</option> </select> The list is populated by java but for testing I disabled the function that clears the "Loading" option and I set it to selected. That way the loading option is highlighted by default and the search function is free to highlight something else, then when I click on the search result it works like it's supposed to. But keeping a highlighted option at the top of the list for that sole purpose isn't very elegant, especially since if you click on it the onchange function tries to execute and generates errors. The only solution I can think of is to use java to generate another option way at the bottom of the list that has the selected attribute but I don't quite know how to do that. Does anyone have any thoughts on what I can do? Hello all, I made a fade script that will fade any element in or out. Works great on all browser I've tested but IE 7. With IE I have only tested this will IE 8 and IE 7. IE 7 the effect doesn't work. No error message or anything. I'm unsure what to do from here. I was hoping I could find some help here. Code: function fade(obj, duration, toggle) {
steps = 1000;
elem = document.getElementById(obj);
function fadeIn() {
for(var i = 0; i <= 1; i+=(1/steps)) {
setTimeout("elem.style.opacity = "+ i +"", i * duration);
setTimeout("elem.style.filter='alpha(opacity="+ i * 102 +")'", i * duration);
}
}
function fadeOut() {
for(var i = 0; i <= 1; i+=(1/steps)) {
setTimeout("elem.style.opacity = "+ (1-i) +"", i * duration);
setTimeout("elem.style.filter='alpha(opacity="+ (1-i) * 102 +")'", i * duration);
}
}
/* One for Fade in and anything will be fade out*/
if(toggle == 1) {
fadeIn();
}
else {
fadeOut();
}
}
Thanks, Jon W I'm looking for something that allows me to add tags to a photo like this website: http://fukung.net By clicking add tag it opens a input box and once added adds to a DB. How would I do something along those lines? Hi, hope someone can see an answer here. I have 4 div tags which are hidden to begin with from the css as shown below: Code: #story1 {float:left;width:100%;display:none;background:#333;color:#fff;vertical-align:top;}
#story2 {float:left;width:100%;display:none;background:#333;color:#fff;vertical-align:top;}
#story3 {float:left;width:100%;display:none;background:#333;color:#fff;vertical-align:bottom;}
#story4 {float:left;width:100%;display:none;background:#333;color:#fff;vertical-align:bottom;}
The contents of these is pulled out of a db and so the quantity of text changes (within certain parameters) and so the size of the divs changes, hence no height: setting. I know I could get around this by setting an absolute height and using overflow to show a scrollbar but I would rather not have a scrollbar as the amount of text will only be 100-200 words. Elsewhere I have used the following script to equalise div tags Code: if (document.getElementById("member1").offsetHeight < document.getElementById("member2").offsetHeight){
document.getElementById("member1").style.height = document.getElementById("member2").offsetHeight + "px";
}
else {
document.getElementById("member2").style.height = document.getElementById("member1").offsetHeight + "px";
}
I tried this for my div tags but because they initially start with display:none it sets the height of them to zero. Is there a simple way to make all of these the same height whilst they are hidden? Where to put the <ol>&&</ol> tags so everytime i run the javascript it numbers each indivdiual items which the javascript is looping. Code: <table border="2"table align="center" cellpadding="40">
<tr>
<th width="80%"> Questions & Time</th>
<th>Status</th>
</tr>
<tr>
<td><% for (int i=0; i < theList.size(); i++) {%>
<tr>
<td><%= theList.elementAt(i)+ " " + theTime.elementAt(i) %>
<% }%>
</td>
<td>Where is the pending goes:</td>
</tr>
<tr>
</table>
I forgot how to do this. I did this a long time ago but have deleted the example. I want to absolute position 11 scrolling div tags of the same dimensions with the same top and left positions. In other words, on top of each other. This is easy. What I can't remember how to do is trigger them so one shows up and the others are hidden. Code: <style>
.one {
position:absolute;
top:200px;
left:0px;
background:skyblue;
width:250px;
height:250px;
}
.two {
position:absolute;
top:200px;
left:0px;
background:aqua;
width:250px;
height:250px;
}
</style>
<input type="button" onClick="" value="one">
<input type="button" onClick="" value="two">
<div class="one">one</div>
<div class="two">two</div>
Hi, I have a regular expression which removes anything between <script> and </script> tags. The problem comes when there is more than one on a page, eg. Code: <script>lose this</script> content I want to keep <script>lose this</script> Everything in that string is removed... how can I limit it to complete tags only? I did a search but could only find ones that either remove tags only, or have the same problem as mine. Cheers, Gus Hopefully this is a simple problem with a simple solution but I cannot find it as of yet. Here is an example: The following is a link that goes nowhere, it has a mouseover listener function registered. The function works in firefox but not IE. I have also tried to 'attachEvent' for IE instead of 'addEvent' but this too does nothing. Is it possible to attach a mouseover to an anchor tag in ie or am I wasting my time? Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<script type="text/javascript">
window.onload = function(){
document.getElementById('test').addEventListener('mouseover',function(e){ alert("mouseover"); }, false);
}
</script>
</head>
<body>
<a href="#" id="test">mouseover</a>
</body>

-Jon I am trying to replace all newline characters with <br /> tags. The following two javascript functions that I've found, work in Firefox but do not work in Internet Explorer (I have version 7 installed on my machine). I would really appreciate any pointers on how to get this done. Thank you! Joe PS: I am using jQuery to call these functions. And this is how my JSP page looks like. Code: <html>

var replaceString = '<br />';
return myString.replace(regX, replaceString);
}
$().ready(function(){
$(".replace-text").each(function(i) {
var sBody = $(this).html();
$(this).html(replaceNewLine(sBody));
});
});
/*

I'm using forum with bb rich text editor, the problem that sometimes when a user copy and paste content, there ere extra codes that are not supported like: Code: [highlight=#ff0000][/highlight] [blockquote][/blockquote] [CENTER ALIGN=CENTER][/CENTER ALIGN] Can you help me to write a script that automatically reformat the html content when pasted and only keeps specified tags like [img],[url],[b], defined in array ... If it is not possible to reformat content when paste, I can add a button to the editor and call that function to format the content and return plain text with a specific tags. I tried this script: Code: function removeHtmlTag(strx){
if(strx.indexOf("[")!=-1)
{
var s = strx.split("[");
for(var i=0;i<s.length;i++){
if(s[i].indexOf("]")!=-1){
s[i] = s[i].substring(s[i].indexOf("]")+1,s[i].length);
}
}
strx = s.join("");
}
return strx+'';
}
It made to strip html tags, I replaced <> with [], It removes all tags and don't put space instead of the removed tags, example: Code: hello[h1]Name[/h1] Will be like : helloName ??? I got an idea to make a stupid trick, like converting [IMG] to {IMG} and run that function and re convert {IMG} to [IMG] ... Please help, I'm not good in Regular Expressions. Thanks for your time, Regards. I'm working on a greasemonkey script that requires me to append a tag before each instance of a tag with a specific class name. It works when there's no parent tags but when it goes into levels deep it doesn't work. So how can I use insertbefore?

I am just playing around a bit with forms and don't really have concrete knowledge. What I have done is created a form. Asking for first name, last name, age and email. When the user clicks the submit button I want 2 functions to run, the first checking the input is correct and also making sure all fields have a value. Once everything is checked and is O.K I want to go into another function which sends all this information to an array one by one. I am having difficulty accessing each individual input tag. I could achieve what I want to do, but it will take double the lines of code because each input has a different 'name'. So, what I am trying to do is access the input tags the same as you would do an array. Here is my code: HTML: Code: <form name="regForm" id="form"> <fieldset> <legend>Real Heroes - Registration Form</legend> <p>First Name:<input type="text" size="30" maxlength="20" name="txtFirstName" /></p> <p>Last Name:<input type="text" size="30" maxlength="20" name="txtLastName" /></p> <p>Age:<input type="text" size="30" maxlength="3" name="txtAge" /></p> <p>Email Address:<input type="text" size="30" maxlength="50" name="email" /></p> <p><input type="button" value="Submit Registration" name="butChkForm" onclick="callFuncs_onclick()" /> <input type="reset" value="Reset" name="resetForm" /></p> </fieldset> </form> JavaScript: Code: //CALLING THE FORM SCRIPTS//
function callFuncs_onclick()
{
chkForm_onclick();
creatingDatabase_onclick();
}
//**************FORM VALIDATION***************//
function chkForm_onclick()
{
var theForm = document.regForm;
if (theForm.txtFirstName.value == "" || theForm.txtLastName.value == "" || theForm.txtAge.value == ""
|| theForm.email.value == "")
{
alert("Please complete all of the form.");
if (theForm.txtFirstName.value == "")
{
theForm.txtFirstName.focus();
}
if (theForm.txtLastName.value == "")
{
theForm.txtLastName.focus();
}
if (theForm.txtAge.value == "")
{
theForm.txtAge.focus();
}
if (theForm.email.value == "")
{
theForm.email.focus();
}
}
else if (isNaN(theForm.txtAge.value))
{
alert("That is not valid input for this field. Please re-enter your age.");
theForm.txtAge.focus();
}
else
{
alert("Thank you for completing the form, " + theForm.txtFirstName.value);
}
}
function creatingDatabase_onclick()
{
var form = document.regForm;
var index = form.input[0].value;
alert(index);
}
I'm not quite sure where I am going wrong. Please note that these functions really labour the point, I know I have way too many lines of code but I am still very amateur with JS. Thank you for any help/information. Kind Regards, LC. I have been working on this code for days and I cannot get it right!!! Can anyone please give me any pointers. It should have an error message that pops up on same line as text boxes when into is not entered property! Thanks in advance! NewBanks <html xmlns="http://www.w3.org/1999/xhtml"> <head> <script type="text/javascript"> function validate(){ var errorList = new Array(); var eMail = document.getElementById("email").value; var passwrd = document.getElementById("password").value; var cPassword = document.getElementById("confirmPassword").value; var secQuest = document.getElementById("securityQuestion").value; var secAns = document.getElementById("securityAnswer").value; var regEx = /^\s*[\w\\+_]+(\.[\w\\+_]+)*\@[\w\\+_]+\.[\w\\+_]+(\.[\w\\+_]+)*\s*$/; if(!regEx.test(eMail)){ errorList[errorList.length] = ("You must enter a valid email address!<br/>"); valid = false; } if(passwrd == "" || passwrd.length <6){ errorList[errorList.length] = ("Your password must be 6 characters long! <br/>"); valid = false; } if(passwrd != cPassword){ errorList[errorList.length] = ("Passwords do not match! <br/>"); valid = false; } if (secAns == ""){ errorList[errorList.length] = ("Please enter your Security Answer! <br/>"); valid = false; } if(errorList.length > 0){ for(var i = 0; i < errorList.length; i++){ document.getElementById("errors").innerHTML += errorList[i]; } return false; } else return true; window.onload = function() { 0(); } } </script> </head> <body> <form id="login" action="confirm.html"method="get" onsubmit="return validate();"/> Email: <input type="text" name="email" id="email" onblur="validate(this);" /> <br/><span id = "Invalid Email"></span> Password: <input type="text" name="password" id="password" onblur="validate(this);" /> <br/><span id = "Incorrect Password"></span> Confirm Password: <input type="text" name="password" id="confirmPassword" onblur="validate(this);" /> <br/><span id = "Invalid password"></span> Security Question: <select id = "securityQuestion" onblur="validate(this);"> <option value= "maiden" >What is your mother's maiden name </option> <option value= "animal"> What is your favorite animal </option> </select> <br/> <input type="text" name="securityAnswer" id="securityAnswer" onblur="validate(this);" /> <br/><span id = "Security Answer does not match"></span> <p><input type = "Submit" /></p> <span id = "errors"> </span> </form> </body> </html> As is in order to trigger the text turning back to black it seems I need to put the lines like below one by one for all the id's. I'm wondering if there is a less lengthy way to get this done? // JavaScript Document function CheckTheForm() { var result = true; var msg=""; document.getElementById('maincontactemail').style.color='#000000'; document.getElementById('maincontact').style.color='#000000'; |
