I've been battling with this for a couple of hours now. I bet the answer is simple.
I want to take "text (just the text in here) more text" and end up with "just the text in here" No brackets
Basically I'm trying to strip a "url(address here)"
My regex literal so far is /[^(].*[^)]/g
This would work say for "(hello there)" -> "hello there", but fails for "text(hello there)text"
I have the folowing string:
"url(http://www.somelocation/anaywhere/image.jpg)" stored in the variable
str_image and I want to extract the string between the brackets. I have:
ar_match=str_image.match("url([.]*)");
it returns
0=url
1=
How do I get this to work?
Can't figure out why the pattern will match a period but not a square bracket.For example, it will match "See Jack run." but not "See [Jack] run.". Just ignores the brackets.
Code:
var title = note_title.value;
// validate periods and brackets
[code]....
I'm hoping that someone can help me with a question I have about javascript syntax.
I got an html page that uploads an image and some text field to a database.
What I'd like to do is modify the content of one of the textfields prior to it being submitted to the database. Specifically, I need to append the contents of one of the fields to another.
The problem that I've encountered is that the textfield name contains square brackets , ‘extra_fields[Price]'
I've identified the square brackets as being the problem by changing the textfield's name to one that doesn't contain square brackets ,extra_fieldPrice for example and the script works fine.
Unfortunately, in the real world application of this page, I can't change the textfield name.
The specific part of the html page that's giving me problems is:
While trying to get a selector to work with ids that include square brackets, I searched the forum and found that I needed to escape the brackets with '\'. However, while this works with my fiddle: can't get the exact same selector to work within my page in either FF or Safari. I've triple-checked the id and it is correct; I know that jQuery is working on the page because changing the selector to$('.nameinput') gives the expected results. can't change the id because I'm working within an existing application; I know I could add a class to the input and use that as the selector instead. I'd prefer not to and would just like to figure out why this isn't working.

Any suggestions on how the javascript below should be changed so it will work with checkboxes that have brackets in the name? (I'm using foreach in php, and can't seem to get the php to work/work correctly without using them.)

Does this work in all browsers?

View 6 Replies View RelatedI'm looking for javascript to analyze the contents of a textbox and replace the contents with the appropriate date. To make that a little clearer, if the user types 'tomorrow' then when they tab/move onto the next text box the 'tomorrow' text should be replaced with the date for tomorrow in the format dd/mm/yyyy, if the user enters '1 week' then the text should be replaced with the date in one week in the format dd/mm/yyyy etc.

I have a function which validates the password if there is a number:
-------------------------------------------------
function findNumeric(str_obj){
regEx = /d/;
if (str_obj.match(regEx))
return true;
else
return false;
}
--------------------------------------------------
The problem arises when I put a password with a space in between e.g:
'test test1'. The fucntion returns false. I've tried 's' in the
regEx but the user can put the space anywhere..
Any idea how to solve this problem as I should be able to put any
alplanumeric value into the password, including space.
I have a variable named "acct". I first want to remove any "-" characters
from it's value. After this I want to verify that we have only exactly 12
digits in the variable.
Unfortunately I'm pretty green as far as using RegEx.
/d{12}/.test(acct); should do the second part, but how do I do the first?
Basically i want to get the current url, and then replace http:// with
something else.
Here is the current code.
var current_url = window.document.location;
var re = new RegExp("http://", "g");
if(re.test(current_url)) {
me = current_url.replace(re,"http://www.addme.com/");
window.alert("found :: " + me + " :: " + current_url);
} else {
window.alert("not");}
if my page was http://ww.google.com 'd get the alert to be:
found :: undefined :: http://www.google.com.
I dont understand why i am getting undefined. When re.test() works.
surely that means the regex is correct.
Trying to match the entire following object literal code using a RegEx.
var Punctuators = { '{' : 'LeftCurly', '}' : 'RightCurly' }
Variations on the idea of using /var.*{.*}/ of course stops at the
first }.
I was using the following code:
element.value = element.value.replace(/ /g,'');
to remove all the spaces in a string.
However in IE6 it complained with and "Expected ')'" error.
How can I tell IE6 to replace just spaces (i.e. not using s)?
I tried / / and /[ ]/ but neither of them worked either.

ok heres a regex
/^(?=.*d)(?=.*[A-Z])(?=.*[a-z]).{8,16}$/
which checks I have at least one lowercase letter, one uppercase letter and one number and the string is between 8 and 16 characters.I have adapted this from another source and it works as intended on all browsers but not IE7 or IE6 (oh microsoft why do you make my life so hard)This works fine in all other browsers (IE8 is fine) but doesnt work in IE6 or IE7
I'm writing an ECMAScript tokeniser and parser and trying to find out if I can eliminate the switching from tokenising "/" as start of regex or the division operator depending on the parser feedback - essentially, if I can make the tokeniser independent of the parser. (I have a gut feeling this needs too much special casing to be worth it). Code:

I have a bunch of text that I want to split into an array of sentences. I have the following code that works just fine on FF and Chromium, but ofc has to fail on the pile of *** that is IE [code]...
It does not produce any errors, but the resulting array often has empty strings as value instead of the sentences that should be there. how to do this in a way it also works on IE?
i have the following regex:
(s*{s*(<?)s*(>?)s*}s*)
this needs to be able to match a string and make the following replacements:
if the string matches without < or >, replace the match with a space, a replacement string, and another space. if < matches also, do not add the left space. if > matches, do not add the right space. if < and > match, do not add the beginning or ending space
Old {} String => Old Replacement String
Old {<} String => OldReplacement String
Old {>} String => Old ReplacementString
Old {<>} String => OldReplacementString
this will have to be done a LOT of times, so efficiency is very important the answer in php is below. can anyone help me figure out how to do it in javascript? PHP Code:
In have a string of data like so:
<div id="feedback">
<p>[DEC 12th Anthony]I like it[DEC 12th Anthony]I agree</p>
</div>
I'm trying to use regex to add a <br /> before each item in hard brackets so the comments are broken out. Here's what I've tried.
re = /(.*])/gi;
vTemp = aSourceObject.innerHTML.replace(re,"<br />$1");
What I end up getting is:
<div id="feedback">
<p><br />[DEC 12th Anthony]I like it[DEC 12th Anthony]I agree</p>
</div>
It gets it right, but only for the first item, not the second one. If I tell it to put the <br /> after then I get
<p>[DEC 12th Anthony]I like it[DEC 12th Anthony]<br />I agree</p>
So its like its reading the entire section in brackets as one match instead of 2 seperate matches..
I need information about javascript & regular expression.please suugest me any book or tutorial web site.
