Part of string

I have problem with part of string extraction. I'm developing a moviecard for eXtreme movie manager in HTML format.

Here is my problem:

I have a string variable "_MOVIE_GENRE_" in which can be entered for example "comedy/drama/action". I want to create script that for every genre will be inserted a gif pic.
That i do so far:

var genre="_MOVIE_GENRE_";
var comedy="<IMG src='moviecards/cortexmod/comedy.gif' border='0' align='absbottom' alt='comedy' width='25' high='12'>";
var drama="<IMG src='moviecards/cortexmod/drama.gif' border='0' align='absbottom' alt='drama' width='25' high='12'>";

switch(genre) {
case "Comedy":
document.all.genre.insertAdjacentHTML("AfterEnd",comedy);
break;
case "Drama":
document.all.genre.insertAdjacentHTML("AfterEnd",drama);
break;
}
.
.
.
.
Later in code i insert the gifs with:
&nbsp;<genre id="genre">

That works fine if the string is "comedy" OR "drama" but i want to insert two gifs if string in the var "_MOVIE_GENRE_" is "comedy/drama"

Any help will be welcome.

Thanx you all!

P.S. Forgive my english.

a more efficient way to write that might be:



This stores less repetitive information in a variable.

As for the parsing of a string, you might want to look at Javascript's indexOf() function in combination with the substr() function. Then just pop them all into an array and use Javascript's for (var i in object) (equivalent to Perl's foreach structure) to print the HTML

Thanx for quick reply.

Ive puted this together and i wonder if its ok:

var genre="_MOVIE_GENRE_";
var comedy="comedy.gif";
var drama="drama.gif";

var comedy1=genre.indexOf("Comedy");
if (comedy1 >= 0) {
document.all.genre.insertAdjacentHTML("AfterEnd","<IMG src='moviecards/cortexmod/"+comedy+" border='0' align='absbottom' alt='comedy' width='25' height='12'>");
}

Thanx.

So long as it works, I guess its okay.

I was thinking something along the lines of searching for the index of the delimiting character, in your example it was a slash (/)... you can then form an array of the genres...

where is genre being set?

if you're setting it to "_MOVIE_GENRE_" then when would you ever find the word "Comedy"?

I finaly put together my code. I never thought it is so simple. Here is what i did:

var genre="_MOVIE_GENRE_";
var separator=" - "
var comedy=genre.indexOf("Comedy");
if (comedy >= 0) {
document.all.genre.insertAdjacentHTML("AfterEnd","<IMG src='moviecards/cortexmod/comedy.gif' border='0' align='absbottom' alt='Comedy' width='30' height='30'>"+ separator);
}
var thriller=genre.indexOf("Thriller");
if (thriller >= 0) {
document.all.genre.insertAdjacentHTML("AfterEnd","<IMG src='moviecards/cortexmod/thriller.gif' border='0' align='absbottom' alt='Thriller' width='30' height='30'>"+ separator);
}
var action=genre.indexOf("Action");
if (action >= 0) {
document.all.genre.insertAdjacentHTML("AfterEnd","<IMG src='moviecards/cortexmod/action.jpg' border='0' align='absbottom' alt='Action' width='30' height='30'>"+ separator);
}
.
.
.
.
and so on...
Thanx for the tip.

P.S.: "_MOVIE_GENRE_" is a tag which this program eXtreme movie manager imports a contents of a field named "MOVIE GENRE" and tag "_TMOVIE_GENRE_" imports name of that field.
