Question

After searching for an answer in other posts, I felt I have to ask this.
I looked at How do I check if an array includes an object in JavaScript?
and Best way to find if an item is in a JavaScript array? and couldn’t get the code there to work.

I am capturing an html embed code into an array, so each item is a line of html code.

for example:

i[0]='<param name=\"bgcolor\" value=\"#FFFFFF\" />'
i[1]='<param name=\"width" value=\"640\" />'
i[2]='<param name=\"height\" value=\"360\" />'   
i[3]='more html code' 

I want to search this array and find the line where the word ‘height’ is.

So ideally, I’d like to write a function that returns the index of the item where ‘height’ appears.

Fortunately, there are no duplicates in this array, so there’s only one occurrence.

with simple object search I get ‘false’ returns.

Any idea?

Answer 1

It’s as simple as iterating the array and looking for the regexp

function searchStringInArray (str, strArray) {
    for (var j=0; j<strArray.length; j++) {
        if (strArray[j].match(str)) return j;
    }
    return -1;
}

Edit – make str as an argument to function.
