I have a string, for example testserver\sho007, how do I use jQuery to return only sho007?
You can do it simply with javascript
var my_string="testserver\sho007";
var left_side=my_string.split("\\")[0];
var right_side=my_string.split("\\")[1];
edited to add the double slash as Eric mentioned
You may use
text.substring(fromindex,toindex)
Use Regular Expressions if you are sure that the text you want is going to be after the slash.
split the string using "\" and get the position [1], always start with [0]
exp:
html:
<a class='test'>testserver\sho007</a>
js:
$(document).ready(function(){
var a = $(".test").text();
var aResult = a.split("\\")[1];
});
testserver = [0]
sho007 = [1]

I have the following strings
"www.mywebsite.com/alex/bob/a-111/..."
"www.mywebsite.com/alex/bob/a-222/..."
"www.mywebsite.com/alex/bob/a-333/...".
I need to find the a-xxx in each one of them and use it as a different string.
Is there a way to do this?
I tried by using indexOf() but it only works with one character. Any other ideas?
You can use RegExp
var string = "www.mywebsite.com/alex/bob/a-111/...";
var result = string.match(/(a-\d+)/);
console.log(result[0]);
or match all values
var strings = "www.mywebsite.com/alex/bob/a-111/..." +
"www.mywebsite.com/alex/bob/a-222/..." +
"www.mywebsite.com/alex/bob/a-333/...";
var result = strings.match(/a-\d+/g)
console.log(result.join(', '));
Use the following RegEx in conjunction with JS's search() API
/(a)\-\w+/g
Reference for search(): http://www.w3schools.com/js/js_regexp.asp
var reg=/a-\d{3}/;
text.match(reg);
I can't replace the substring in a string:
var source = "div.col-md-4.fields:visible:eq(0) div.panel-body select:eq(0)";
var modified = source.replace(/visible:eq(0)/g, "1234");
I wonder why does modified have the same value as source?
You should not use regular expressions here but a simple string replace function. It will run faster and regular expressions were not made for simple tasks like this as they will run slightly slower than the simple replace function. Using regular expressions here is like using a nuke to open a water bottle, rather prefer simplicity, if a developer sees this code he will like the simplicity.
Change your second line to this one:
var modified = source.replace("visible:eq(0)", "1234");
You need to escape the brackets
var source = "div.col-md-4.fields:visible:eq(0) div.panel-body select:eq(0)";
var modified = source.replace(/visible:eq\(0\)/g, "1234");
console.log(source);
console.log(modified);
You just need to escape your chars like this Demo: http://jsfiddle.net/cvW24/1/
hope rest help the cause :)
if you keen:
Need to escape a special character in a jQuery selector string
http://api.jquery.com/category/selectors/
code
var source = "div.col-md-4.fields:visible:eq(0) div.panel-body select:eq(0)";
var modified = source.replace(/visible:eq\(0\)/g, "1234");
alert(modified);
Because your regular expression does not match the string. You need to escape the parenthesis.
var modified = source.replace(/visible:eq\(0\)/g, "1234");
I have this string:
var str = "jquery12325365345423545423im-a-very-good-string";
What I would like to do, is removing the part 'jquery12325365345423545423' from the above string.
The output should be:
var str = 'im-a-very-good-string';
How can I remove that part of the string using php? Are there any functions in php to remove a specified part of a string?
sorry for not including the part i have done
I am looking for solution in js or jquery
so far i have tried
var str="jquery12325365345423545423im-a-very-good-string";
str=str.replace("jquery12325365345423545423","");
but problem is numbers are randomly generated and changed every time.
so is there other ways to solve this using jquery or JS
The simplest solution is to do it with:
str = str.replace(/jquery\d+/, '').replace(' ', '');
You can use string replace.
var str = "jquery12325365345423545423im-a-very-good-string";
str.replace('jquery12325365345423545423','');
Then to removespaces you can add this.
str.replace(' ','');
I think it will be best to describe the methods usually used with this kind of problems and let you decide what to use (how the string changes is rather unclear).
METHOD 1: Regular expression
You can search for a regular expression and replace the part of the string that matches the regular expression. This can be achieved through the JavaScript Replace() method.
In your case you could use following Regular expression: /jquery\d+/g (all strings that begin with jquery and continue with numbers, f.e. jquery12325365345423545423 or jquery0)
As code:
var str="jquery12325365345423545423im-a-very-good-string";
str=str.replace("/jquery\d+/g","");
See the jsFiddle example
METHOD 2: Substring
If your code will always have the same length and be at the same position, you should probably be using the JavaScript substring() method.
As code:
var str="jquery12325365345423545423im-a-very-good-string";
var code = str.substring(0,26);
str=str.substring(26);
See the jsFiddle example
Run this sample in chrome dev tools
var str="jquery12325365345423545423im-a-very-good-string";
str=str.replace("jquery12325365345423545423","");
console.log(str)
I need to capture the price out of the following string:
Price: 30.
I need the 30 here, so I figured I'd use the following regex:
([0-9]+)$
This works in Rubular, but it returns null when I try it in my javascript.
console.log(values[1]);
// Price: 100
var price = values[1].match('/([0-9]+)$/g');
// null
Any ideas? Thanks in advance
Try this:
var price = values[1].match(/([0-9]+)$/g);
JavaScript supports RegExp literals, you don't need quotes and delimiters.
.match(/\d+$/) should behave the same, by the way.
See also: MDN - Creating a Regular Expression
Keep in mind there are simpler ways of getting this data. For example:
var tokens = values[1].split(': ');
var price = tokens[1];
You can also split by a single space, and probably want to add some validation.
Why don't you use this?
var matches = a.match(/\d+/);
then you can consume the first element (or last)
my suggestion is to avoid using $ in the end because there might be a space in the end.
This also works:
var price = values[1].match('([0-9]+)$');
It appears that you escaped the open-perens and therefore the regex is looking for "(90".
You don't need to put quotes around the regular expression in JavaScript.
Let's say I have something like this:
var location = '/users/45/messages/current/20/';
and I need to end up with this:
'/45/messages/current/20/'
So, I need to erase the first part of /whatever/
I can use jquery and/or javascript. How would I do it in the best way possible?
To replace everything up to the second slash:
var i = location.indexOf("/", 1); //Start at 2nd character to skip first slash
var result = location.substr(i);
You can use regular expressions, or the possibly more readable
var location = '/users/45/messages/current/20/';
var delim = "/"
alert(delim+location.split(delim).slice(2).join(delim))
Use JavaScript's slice() command. Do you need to parse for where to slice from or is it a known prefix? Depending on what exactly you are parsing for, it may be as simple as use match() to find your pattern.
location.replace("/(whatever|you|want|users|something)/", "");
find the 2nd index of '/' in the string, then substr from the index to the end.
If you always want to eliminate the first part of a relative path, it's probably simplest just to use regular expressions
var loc = '/users/45/messages/current/20/';
loc.replace(/^\/[^\/]+/,'');
location.replace(/\/.*?\//, "/");
location.replace(/^\/[^\/]+/, '')
