javascript - Recognize in which tag given word is? -

next, have div below tags contains type [info] [/ info]:

<div id="tags"> [info id=“rol”] rol -> greatest project add in same people [/info]   [info id=“add”] add -> moment pick ball , shoot in cars [/info]   [info id=“tree”] tree -> tree of views in other dimensions [/info] </div> 

i created search engine made ​​in jquery, type in text field , click search saves variable 'searchtext', can see below:

$(“#buttongo").click(function() { var searchtext = $(‘#searchfield’).val(); }); 

after have is:

1. take value stored in variable searchtext, , text in div

2. then find text give warning showing in located info tag, eg:

searchtext var = "views in other";

  must recognize tag [info id = "tree"] [/ info] because text located within tag .... , return alert should come follows:

(tag: info, id: tree, desc:"tree -> tree of views in other dimensions")

i not know start, can give me hand?

to follow on earlier comment, can create info object this:

var treeinfo = new object(); treeinfo.id = "tree"; treeinfo.description = "tree -> tree of views in other dimensions" 

next, create array hold info objects if desire:

var infoarray = []; infoarray.push(treeinfo);  

then when you're checking provided text, use simple loop. eg:

for (var = 0; < infoarray.length; i++) {      if (infoarray[i].description.indexof(searchtextvar) != -1){        //found correct text, something.      } } 

it better wrap for loop in function , return info object when find match.

you can use path if don't want store info objects in div.

edit address comment array size: if want use huge block of text can use method below though isn't cleanest/fastest. 1 way of solving problem.

use regex this: \[info id=.+?] once starting index of searchtextvar. , then, find closing tag same index \[/info]. now, substring of searchtextvar using indices regex matches contain tag.

after that, resulting string should right tag , can parse text , display appropriate.

if you're dealing many tags, might not best idea store them in browser... consider using database or other storage mechanism
