How do we trim out or remove a part of a URL or path?
eg. http://www.mywebsite/folder/somefile.htm ----I want to trim
http://www.mywebsite/folder/ so All I have left is the file name.
<script language="JavaScript">
var pathtotrim = location.href;
document.write (pathtotrim);
</script>
Using Regular Expressions (JavaScript 1.2/JScript 4+) :
String.prototype.lTrim =
function()
{
return this.replace(/^s+/,'');
}
String.prototype.lTrim =
function()
{
return this.replace(/s+$/,'');
}
String.prototype.trim =
function()
{
return this.replace(/^s+|s+$/g,'');
}
or for all versions (trims characters ASCII<32 not true
"whitespace"):
function LTrim(str) {
for (var k=0; k<str.length && str.charAt(k)<=" " ; k++) ;
return str.substring(k,str.length);
}
function RTrim(str) {
for (var j=str.length-1; j>=0 && str.charAt(j)<=" " ; j--) ;
return str.substring(0,j+1);
}
function Trim(str) {
return LTrim(RTrim(str));
}

Does java script provides inbuilt trimming function, if not then what
is the solution.
Is there really no string trim function in JS?
Code:
function trim(s)
{
return rtrim(ltrim(s));
[code].....
for all your javascript trimming needs...
function trim(inputString) {
if (typeof inputString != "string") return inputString;
return inputString
//clear leading spaces and empty lines
.replace(/^(s|
|
)*((.|
|
)*?)(s|
|
)*$/g,"$2")
//take consecutive spaces down to one
.replace(/(s(?!(
|
))(?=s))+/g,"")
//take consecutive lines breaks down to one
.replace(/(
|
)+/g,"
")
//remove spacing at the beginning of a line
.replace(/(
|
)s/g,"$1")
//remove spacing at the end of a line
.replace(/s(
|
)/g,"$1");
}
I'm working with SageCRM. When SageCRM outputs the company address, I kid you not, it outputs the value and then a crap ton of HTML non-breaking spaces, a break tag and then repeat for the other address lines.My client added a button to the page via the customization function that links over to MapQuest. But, all those non-breaking spaces mess up the URL.I'm trying to fix it, but I'm having some trouble and thought I'd throw it out to you all.
Code:
// Ninja'd this from somewhere to trim whitespace.
function trim(stringToTrim) {
[code]....
I have the following script that converts line breaks from plain text into HTML formatted paragraphs. It takes plain text from one text area field and outputs the new formatted text into another text area field.
function convertText(){
var noBreaks = document.getElementById("oldText").value;
noBreaks = noBreaks.replace(/

I have a form in my homepage which takes some values. In that, a text box takes multiple values seperated by spaces. I have allowed only alphanumeric characters in that with the following code.

This works fine in FireFox:
$("#listname").val().trim()
But in safari it errors: $("#listname").val().trim() while this does work, $("#listname").val()
Why is that?
I am trying to make a simple trim function but this doesnt works.
function tr(input){
var i;
var str;
for(i=0; i<input.length-1; i++){
if(text.charAt(i)==" "){
str+=""+text.charAt(i)
} return str
}}
My trim() function seems to halt JavaScript execution in Chrome.
Code:
function trim(s) {
s = s.replace(/(^s*)|(s*$)/gi,"");
s = s.replace(/[ ]{2,}/gi," ");
[code]...
It works in IE and firefox.. no it doesn't.
Is there a way of trimming the value before checking it so that a space for example would still be NULL "".
Code:
if(document.sendmail.emailsubject.value == '')
{
msg += "Subject cannot be left blank.
";
error = true;
}
Just wanted to share two handy RegEx expressions to strips leading and
trailing white-space from a string, and to replace all repeated spaces,
newlines and tabs with a single space.
* JavaScript example:
String.prototype.trim = function() {
// Strip leading and trailing white-space
return this.replace(/^s*|s*$/g, "");
}
String.prototype.normalize_space = function() {
// Replace repeated spaces, newlines and tabs with a single space
return this.replace(/^s*|s(?=s)|s*$/g, "");
}
" one two three
".trim(); // --> "one two three"
" one two three
".normalize_space(); // --> "one two three"
Picture a table where each cell row is 50px tall, with 3 to 5 columns of varying length. For example: thumbnail, name, description, price, options. The thumbnail will always be the same size, but for efficiency of space, nothing else is.
My question is one of overflow. With long descriptions, overflow:hidden will keep things clean. But the most aesthetic presentation would be todynamically truncate the description with ellipses (...) somewhere just before the text runs off the end of the cell (like the ubiquitous [More...] feature, but first filling the cell as much as possible).
This is a typographically desirable feature, and I can come pretty close with php

how to trim strings in Javascript with variable lengths? For example:
My Option 1 (+$10.00)
Short Option (+$5.00)
Really long Option
I only want to trim off the (+$10.00) on My Option 1 and the (+$5.00) on Short Option. No trim necessary on Really long Option. When I'm done I want to be left with:
My Option 1
Short Option
Really long Option
If there is a unlimit long textfield, the user can type free text. It means that the client can type

View 1 Replies View RelatedI need help with substring or trim function in javascript. Find below my code. Selection holds the value Select State, and length of the string is 14. I need to equate the Selection value to string "Select State" and execute alert message.
function selected_item() {
if (Selection=="Select State")
alert("Select the State");[code]....
I tried this:
var state=Selection.substring(0,11); and then string would be equated to state variable. But it is not working.
I have a little problem and I hope that I need to get the path of the URL except for the first slash "/". Now if I use window.location.pathname I get an output like this: /about/about/9081ae1b02/
That is almost right but I need to get rid of the first slash (marked in red) so I get: about/about/9081ae1b02/
I'm trying to figure out how to split a url variable... I tried these two ways, with an alert to see my result, but I'm not getting anything.
