Searching string with regular expression

[amollokhande1]

Hi,

I have following string data

Amol\'Lokhande. Now I want to search \' from the string.

I have used following code

sValue="Amol\'Lokhande"
var objRegex =new RegExp("\\\\'","g");
sValue.search(objRegex)

but still it is not working. Can anybody help me to resolve this problem.

What will be the regular expression to search \' string

Regards

this should work:

[CODE=javascript]var sValue = "Amol\'Lokhande ";

var objRegex = new RegExp("\'", "g");

alert(objRegex. test(sValue));
[/CODE]
kind regards

Hi gits

It is not working. If return ture even if we remove \ from the string Amol'Lokhande

for JavaScript the "\'" == "'" ... so the backslash is an escape-char already in the string ... basicly you create a new string "Amol'Lokha nde" in your code ... i've to look deeper into that issue ... don't know a solution other then have the \ escaped already before you try to create a JavaScript object from it ... in case you want to preserve it.

wouldn't it be easier to use a string search? like

if (sValue.indexOf("\'") != -1) { ... }

that would even match ' or wouldn't it? ... may be i miss something?

[Dormilich]

the problem is the original string. try alert(sValue); and you'll see.

yep ... therefore i just suggested to escape that before using it in JavaScript when that chars need to be preserved ... but may be its just misleading? may be we should know whatfor that match should be used ... currently i don't see any problem because the backslash is just dropped from the string by the string-construction itself?

kind regards

searching for the backslash was pointless from the beginning – that's what the alert taught me.

PS: I should have known, I was trying to find "März" in one of my scripts – and failed
