Remove newlines javascript problem - javascript

Hi i need to strip all spaces and newlines from a string in javascript... This is what i use and it doesn't work...
<script language="JavaScript" type="text/javascript">
<!--
var isShift=null;
var isNN = (navigator.appName.indexOf("Netscape")!=-1);
var OP = (navigator.appName.indexOf("Opera")!=-1);
if(OP)isNN=true;
var key;
function shift(event){
key = (isNN) ? event.which : event.keyCode;
if (key==16)isShift=1;
}
function process(event){
key = (isNN) ? event.which : event.keyCode;
if(document.layers&&event.modifiers==4){
isShift=1;
}
if (key==13&&isShift!=1){
var chatmsg = $("#chatmsg");
var cmessage = chatmsg.val();
cmessage = cmessage.replace(/\s/g, '');
if(cmessage=="")
{
document.myForm.chatmsg.value = "";
return false;
}
else
{
sendMsg();
}
}
if (key!=16)isShift=null;
}
//-->
function sendMsg(){
var chatmsg = $("#chatmsg");
$.post("sendchat.php",{ chatmsg: chatmsg.val()} ,
function(data)
{
$("#msgtousr").html(data).show();
$("#msgtousr").html(data).fadeOut(2000);
document.myForm.chatmsg.value = "";
});
}
</script>
<form name='myForm' method='POST' style='margin:0px'>
<textarea name='chatmsg' onkeypress='return process(event)' onkeydown='shift(event)' style='width:278px;height:70px;border:2px solid white;background-color:turquoise;color:blue' id='chatmsg'></textarea>
</form>
This is my chat if it has an error checking if the user typed something in in the javascript i suspect the replace function to misbehave

You want to strip all spaces and newlines? Only one regex is necessary:
cmessage = cmessage.replace(/\s/g, '');

Try...
cmessage = cmessage.replace(/\s/g, '');
\s in this case stands for "all white space" which includes spaces and newline characters.

How to Prevent Spaces to Be Counted as Characters?

I've got a search box and works quite good actually. What it does is that you type something and if it already exists, it shows you the topic. If not, it sends you to page that you can open this topic. When you type "ABC" or "A BC", it's okay but when you try to type "AB" and then try to search, it gives you an error that you need to type at least 3 characters, which is good. But it can be easily done like ("a space space" - counts 3). You may open topics with spaces, sure, but don't want that spaces to be counted. Such as, (hello world) It should be counted as 10 characters, not 11. How to exclude spaces to be counted as characters? It's a project I'm working on to make it better, I have not written all by myself.
Here are my search box's all javascript files which I probably need to edit but don't know how:
<script type="text/javascript">
function formatText(tag) {
var Field = document.getElementById('entry_girdi');
var val = Field.value;
var selected_txt = val.substring(Field.selectionStart, Field.selectionEnd);
var before_txt = val.substring(0, Field.selectionStart);
var after_txt = val.substring(Field.selectionEnd, val.length);
Field.value += '[' + tag + '/]';
}
</script>

My another topic has been marked as duplicate but to be honest, I don't really know how to adapt these suggested lines to my js codes to get it working properly.
var myString = getElementById("input").value;
var withoutSpace = myString.replace(/ /g,"");
var length = withoutSpace.length;
You just take the value, in your case val, and strip out the spaces.
Change this line:
var val = Field.value;
To:
var val = Field.value.replace(/\s/g, '');
I have changed the regex from the solution you've posted with \s, which matches all kinds of space, not just the whitespace character.
You could count all the caracters, including spaces, with this:
var val = Field.value;
var chars = val.length;
Then you can count how many spaces do you have:
var spacesArr = val.split(" ");
var spaces = spacesArr.length;
Finally, if you substract the values, you have the actual characters count:
var actualLength = chars - spaces;

Identifying if code between code tags is JavaScript or HTML

I am trying to match block of code to check if is html or javascript code, i tried doing this but am having problem while when have this html element "<div></div>" or php <? echo '';> inside javascript code it will match it as html element.
Please can someone help me with best way to archive this?
<script>
$(document).ready(function(){
function AssignLang(theLanguage){
var regex = /(<([^>]+)>|<([^>]+)>)/ig;
//var regex = "<(\"[^\"]*\"|'[^']*'|[^'\">])*>";
if(theLanguage.match(regex)){
var lang = 'markup';
}else{
var lang = 'javascript';
}
return lang;
}
$('pre code').each(function () {
var the = $(this).html();
/*I tried here to match from 0 to 50 but is not going to help because if the javascript tag begin with <script> still show as html
var theLanguage = the.replace(/\s/g, '').substring(0,50);
*/
var theLanguage = the.replace(/\s/g, '');
var langType = AssignLang(theLanguage);
$(this).addClass("fullcoded language-"+langType);
alert(theLanguage+"-"+langType);
});
});
</script>
Here am matching code inside pre and code element
<pre><code>
function check() {
var delvar = "<? $_POST["del"]; ?>";
var answer = confirm("Are you sure you want to delete the article?")
if (answer) {
window.location = "adm-site.php?del=" + delvar + "&delete=true";
}
}
</code></pre>
<pre><code>
<select name="del">
<option value="none" SELECTED></option>all articles echo'ed here by php
</select>
</code></pre>
Here is a link to https://jsfiddle.net/ppu9qw3n/
This is the regex I'm using /\w+\s\w+\(\)/i
\w+ matches 1 or more a-z, A-Z, 0-9 and _
\s matches 1 space
\( and \) matches ()
Basically I'm searching for a pattern consisting of function functionName() in the code between code tags. If a match is found then it's JavasScript code or else it's HTML code.
This is how you can implement the JavaScript:
$(document).ready(function(){
var regex = /\w+\s\w+\(\)/i;
$('pre code').each(function () {
var v = $(this).html();
if(regex.test(v)){
alert(v+'-'+'THIS IS JAVASCRIPT CODE')
}
else{
alert(v+'-'+'THIS IS HTML CODE')
}
});
});
Check it here on jsfiddle. It's working.

Validation Output -> Picking up javascript

Why is my code picking up the following error?
Line 32, Column 14: character "<" is the first character of a delimiter but occurred as data
for(i=0; i <= length; i++) {
This message may appear in several cases:
You tried to include the "<" character in your page: you should escape it as "<"
You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&", which is always safe.
Another possibility is that you forgot to close quotes in a previous tag.
Line 32, Column 14: StartTag: invalid element name
for(i=0; i <= length; i++) {
Code:
<script type="javascript">
function randomRange(minVal,maxVal)
{
var randVal = minVal+(Math.random()*(maxVal-minVal));
return (Math.floor(randVal));
}
function GetCaptcha() {
var encStr = "123456789ABCDEFGHJKMNPQRSTUVWXYZ";
var length = randomRange(4,8);
var result = "";
var i = "";
var char = "";
for(i=0; i <= length; i++) {
char = encStr.substr(randomRange(1,encStr.length),1);
result += char;
}
return result;
}
function InitCaptcha() {
var hidFld = document.MyForm.captchaHidFld;
str = GetCaptcha();
hidFld.value = str;
document.getElementById('captchaTxt').innerHTML = str;
document.getElementById('captchaBtn').value = str;
}
function ValidateCaptcha (theForm) {
var inpStr = (document.MyForm.captchaInpFld.value).toUpperCase();
var captStr = document.MyForm.captchaHidFld.value;
if (inpStr.length == captStr.length)
{
if (inpStr.match(captStr)) { return true; }
}
return false;
}
function cmdSubmit(theForm)
{
if (!ValidateCaptcha(theForm))
{
alert ("Please enter valid CAPTCHA Code.");
return false;
}
if (theForm.name.value == "")
{
alert ("Please enter your name.");
theForm.name.focus();
return false;
}
if (theForm.email.value == "")
{
alert ("Please enter your e-mail address.");
theForm.email.focus();
return false;
}
return true;
}
</script>
With that transitional XHTML DOCTYPE you'll need to enclose inline Javascript and CSS like this:
<script type="text/javascript">
//<![CDATA[
/* script here */
//]]>
</script>
Compare these results:
this is invalid
this validates
What are you using to validate this? You could always include the javascript as an external javascript file to get around this?
Also: Make sure the script tag is inside a <head> or <body> element?
Your code looks correct. If you bebug the code partially, i.e. GetCaptcha() using firebug, you will be able to track the error quickly.
or Post the HTML related to this code :)

Javascript - If Last Character of a URL string is "+" then remove it...How?

This is a continuation from an existing question. Javascript - Goto URL based on Drop Down Selections (continued!)
I am using dropdown selects to allow my users to build a URL and then hit "Go" to goto it.
Is there any way to add an additional function that checks the URL before going to it?
My URLs sometimes include the "+" character which I need to remove if its the last character in a URL.
So it basically needs to be "if last character is +, remove it"
This is my code:
$(window).load(function(){
$('form').submit(function(e){
window.location.href =
$('#dd0').val() +
$('#dd1').val()+
$('#dd2').val()+
$('#dd3').val();
e.preventDefault();
});
});
var url = /* whatever */;
url = url.replace(/\+$/, '');
For example,
> 'foobar+'.replace(/\+$/, '');
"foobar"
function removeLastPlus (myUrl)
{
if (myUrl.substring(myUrl.length-1) == "+")
{
myUrl = myUrl.substring(0, myUrl.length-1);
}
return myUrl;
}
$(window).load(function(){
$('form').submit(function(e){
var newUrl = $('#dd0').val() +
$('#dd1').val()+
$('#dd2').val()+
$('#dd3').val();
newUrl = removeLastPlus(newUrl);
window.location.href = newUrl;
e.preventDefault();
});
});
Found another solution using str.endsWith("str")
var str = "Hello this is test+";
if(str.endsWith("+")) {
str = str.slice(0,-1);
console.log(str)
}
else {
console.log(str);
}
Also Matt Ball's Replace method looks good. I've updated it to handle the case when there are multiple + at the end.
let str = "hello+++++++++";
str = str.replace(/\++$/, '');
console.log(str);
<script type="text/javascript">
function truncate_plus(input_string) {
if(input_string.substr(input_string.length - 1, 1) == '+') {
return input_string.substr(0, input_string.length - 1);
}
else
{
return input_string;
}
}
</script>
$(window).load(function(){
$('form').submit(function(e){
var newUrl = $('#dd0').val() +
$('#dd1').val()+
$('#dd2').val()+
$('#dd3').val();
newUrl = newUrl.replace(/\+$/, '');
window.location.href = newUrl;
e.preventDefault();
});
});
Just seems easier.
function removeLastPlus(str) {
if (str.slice(-1) == '+') {
return str.slice(0, -1);
}
return str;
}

checking a pattern present in a string using javascript

How to check if a url or url pattern is presnt or not in a string using javascript.
<script language="javascript">
var str="http://localhost/testprj?test=123213123";
var s=location.href;
if(s.match('/http://localhost/testprj?test=1232/'){
alert('welcome!!');
}
</script>
what i need is to check the url pattern.
complete code
<html>
<head>
</head>
<body>
<style>
.active{
color:#009900;
font-weight:bold;
}
</style>
<div id="menu">
<ul><li>
<ul><li> 0
<a href="html.html" >1</a>
2
</li>
</ul></li>
</ul>
</div>
<script language="javascript">
var c=document.getElementById('menu').getElementsByTagName('a').length;
var v=document.getElementById('menu').getElementsByTagName('a');
var s=location.href;
//alert(s.match('html'));
for(var i=0;i<c;i++){
//alert('href'+v[i].className);
if(v[i].href==location.href){
v[i].className='active';
}
}
</script>
</body>
</html>
this is working fine , but if the get params are cause some problms...
like page.php?page=userlist
works fine
but
like page.php?page=userlist&id=121221
this is the base link url
link
For pattern checking, you will want to look into regular expressions.
What particular pattern do you want to check for? If you just want to check whether a string is a URL, the following code should do:
var myString = "http://blah.com/helloworld/";
if (myString.match(/http:\/\//)) {
alert("'myString' is a URL.");
}
Steve
/http:\/\/localhost\/testprj\?test=1232/.test(s)
I think you just had some minor syntax issues:
var re = /http:\/\/localhost\/testprj\?test=1232/
var s=location.href;
if(s.match(re)) {
alert('welcome!!');
}
note that regular expressions are a data type of their own in javascript: no quotes or anything, just / delimeters
Yes finaly i got the solution
i used the functions
for(var i=0;i<len;i++){
if(strstr(url,a[i].href)) {
a[i].className='active';
}
}
function strstr( url, href) {
var pos = 0;
url += '';
pos = url.indexOf( href );
if (pos == -1) {
return false;
}
else{
if(strcmp(url,href)==0)
return 1;
}
}
function strcmp ( str1, str2 ) {
return ( ( str1 == str2 ) ? 0 : ( ( str1 > str2 ) ? 1 : -1 ) );
}
like this way, its working fine!!!
Thank you
