js regexp problem
- by Alexander
I have a searching system that splits the keyword into chunks and searches for it in a string like this:
var regexp_school = new RegExp("(?=.*" + split_keywords[0] + ")(?=.*" + split_keywords[1] + ")(?=.*" + split_keywords[2] + ").*", "i");
I would like to modify this so that so that I would only search for it in the beginning of the words.
For example if the string is:
"Bbe be eb ebb beb"
And the keyword is: "be eb"
Then I want only these to hit "be ebb eb"
In other words I want to combine the above regexp with this one:
var regexp_school = new RegExp("^" + split_keywords[0], "i");
But I'm not sure how the syntax would look like.
I'm also using the split fuction to split the keywords, but I dont want to set a length since I dont know how many words there are in the keyword string.
split_keywords = school_keyword.split(" ", 3);
If I leave the 3 out, will it have dynamic lenght or just lenght of 1? I tried doing a
alert(split_keywords.lenght);
But didnt get a desired response
