I have problem in removing ' with (blank and no space). Like Kello's to kellos.
I already tried this-
str = str.replace(/[\']/g, '');
But its not working.
Please help.
It actually does work:
var str = 'aa\'bb\'cc';
alert(str.replace(/'/g,'')); // aabbcc
alert(str.replace(/[\']/g,'')); // aabbcc
You do not need a character class, you just have to mask it if you use single quotes in JavaScript.
Also, keep in mind that ' (U+0027) is different from ’ (U+2019) and must be handled separately.
A Kello's
str.replace(/[{\ },{\'}]/g,"");
result AKellos

I have a string which looks like this
var dragdropMatchResponseData = '2838[,]02841[:]2839[,]02838[:]2840[,]02840[:]2841[,]02839';
I want to replace the following
1: '[,]' into ':'
2: '[.]' into ','
I tried the following
console.log(dragdropMatchResponseData.replace({ '[,]': ':', '[:]': ',' }));
and
console.log(dragdropMatchResponseData.replace('[,]', ':').replace( '[:]', ','));
but nothing helped me
I want my end result to look like
'2838:02841,2839:02838,2840:02840,2841:02839';
I don't want to add replace in multiple times, I want to do this at one time,
how can I achieve this?
Try regular expression
dragdropMatchResponseData.replace(/\[,\]/g, ':').replace(/\[:\]/g, ',')
The /g flag is to replace all the occurances within the string.
Hey It can be easily achieved using replace function of JS
var data = '2838[,]02841[:]2839[,]02838[:]2840[,]02840[:]2841[,]02839';
console.log(data.replace(/\[:]/g, ',').replace(/\[,]/g, ':'))
Hi I have some text in following format,
683101,
682303,
682302,
682315,
683581,
686667,
682008,
683572,
683573,
682313,
686672,
683545 etc....
Each line break'ed into next line with "Enter". I have nearly 2000 lines of text like this. i want o display the above string to a single line like this.
683101,
682303,
682302,
682315,
683581,
686667,
682008,
683572,
683573,
682313,
686672,
683545,
686672,
683545 etc..
I think there is some tweak options in CSS for doing this. Is there a way in JavaScript to do this? Actually it is not a requirement for me, am just curious to know how it is done.
Edit:
In My text editor it looks like this,
When i try to run it, this is what i get.
Thats why i want to remove the enter, multiline.......
You can use Regular expression to remove all the linebreaks and replace them using space.
str = str.replace(/\n/g, ' ');
Here, \n will match all the line-breaks, and replace them by space
I have a simple way for this. You can do this without extra code. Just write like this -
var str = "12345,\
234234,\
234324,\
234324,\
234324,\
234234";
now just add a slash
Ok, If you don't want to use the above method then use another plan is -
take inside an array and after that use the join method
var str = [12345,
234234,
234324,
234324,
234324,
234234];
str.join(",");
If we are using ES6, Then we have an elegant way to do this using Backtick -
var str = `12345,
234234,
234324,
234324,
234324,
234234`;
Since your data is already comma separated, you can try to add "[" to the beginning and append " ].toString().replace(/\n/g," ") " to the end of your data to get a single line string like this:
[683101,
682303,
682302,
682315,
683581,
686667,
682008,
683572,
683573,
682313,
686672,
683545].toString().replace(/\\n/g," ")
then you get:
"683101,682303,682302,682315,683581,686667,682008,683572,683573,682313,686672,683545"
I hope this helps :)
If all you want is to put those values in one line then, you can set those values as the value of a textarea field. This will allow you to read all those values into a javascript string. Afterward you can apply the regular expression that Tushar suggested.
See the code segment below:
<textarea id="content">
683101,
682303,
682302,
682315,
683581,
686667,
682008,
683572,
683573,
682313,
686672,
683545
</textarea>
Here is the javascript:
var content = $('#content').val();
var content = content.replace(/\n/g, ' ');
console.log(content);
I'm trying to match #(\w+) in a div content and remove it.
Here's what i've tried : http://jsfiddle.net/mxgde6m7/1/ .
#(\w+) works , but it doesn't replace with space.
var content = document.getElementById('contentbox');
var find = '#(\w+)';
var reg = new RegExp(find, 'g');
var result = content.innerHTML.replace(reg, ' ');
alert(result);
<div id="contentbox">#d test
What i want: <div id="contentbox">test
</div>
Thanks in advance.
EDIT
Okay, one problem solved, another one came up.
My script http://jsfiddle.net/mxgde6m7/9/ works perfectly there, but when i try it on my website, only a half works. The last part where it should replace #(\w+) with space doesn't work at all. If i copy/paste the CONTENT of the function in console(chrome), it works , but if i paste the function and i call it, it doesn't work.
Please help ! I'm stuck.
Using a RegExp constructor, you need two backslashes \\ in place of each backslash \.
var find = '#(\\w+)';
hwnd is correct that you need to double escape \w in your regular expression.
var find = '#(\\w+)';
But, you could also make this code much cleaner by defining a regex literal like so -
var content = document.getElementById('contentbox');
var result = content.innerHTML.replace(/#(\w+)/g, ' ');
alert(result);
Doing it this way doesn't require double escaping, as it's not a string.
I found this snippet somewhere and it works like a charm:
var n = parseInt(e.find("span.favNum").text().replace(/./g, "")) + 1;
If I do it in a similar way it doesn't work anymore.
I do the following:
<div id ="test">6.987</div>
var test = $("#test");
var r = test.text().replace(/./g, "");
console.log("wrong ", r);
I know that I can replace it also like this:
var r = test.text().replace(".", "");
This works.
I would like to understand why the "stolen" snippet is working.
Any idea?
http://jsfiddle.net/nJZMf/3/
The original script is found here: http://wp-svbtle.themeskult.com/
You will find the snippet by viewing the source of index.html and searching for .replace.
You need to escape the "."
test.text().replace(/\./g, "");
The reason that the code in the page you linked to works, where yours doesn't, is that it's not the same regular expression. Here's what I found in that page (and similar code in several places)
r = n.text().replace( /,/g, "" )
where r is a jQuery object.
Note that the regular expression has a , inside the //, not a . like the code you had trouble with.
Comma is not a special character in regular expressions, so it needs no special treatment. Period has a special meaning. As the other answers pointed out, it matches all characters, and you need to prefix it with \ if you want to match . only.
Also note that .replace() is not jQuery code, it's JavaScript.
jQuery's .text() method returns a JavaScript String value. So anything you do with that string - such as the .replace() call - is actually a JavaScript String method.
The distinction is important when you want to research a problem: a search for "javascript string replace" will get you better information than "jquery replace".
It has to be var r = test.text().replace(/\./g, ""); instead of var r = test.text().replace(/./g, ""); because you need to escape the . in order for it to be replaced.
http://jsfiddle.net/mrk1989/nJZMf/4/
Solution because I add \ in var r = test.text().replace(/\./g, "");
The problem was that you did not escape dot.
But keep in mind that:
.replace(".", "");
.replace(/\./g, "");
are two different things.
For example: https://jsfiddle.net/rmhpkz9n/1/
I am using following code, in which i want to replace all ' with ;$39 but its not working fine . It's replace only first ' .
var searchUserName = document.getElementById("ctl00_ContentMain_UserSearchColl").value.replace("/\'/g", ";$39;");
For example: Ram's's .Output: Ram;$39s;$39s
Thanks in advance.
You don't need to put the regexp inside double quotes. Remove them.
value.replace(/'/g, ';$39;')
Also note that you need not "escape" the single quote. (Thanks #Paul S. for pointing)
