Just so that you're aware, JS doesn't provide options for file I/O as would a much more complex language like C++ or Java. You can retrieve data, though, from files, but you cannot write to them. You should look into some AJAX concepts if all you need to do is fetch data.For what you need, an array is pointless, because in essence, a string in just an array of single characters. So to simplify things, just take the string of the 4th line by assigning a variable to it. If you want to test if there are any zeros in it, I'd go with the match() method. You can find its details here.http://www.w3schools.com/jsref/jsref_match.aspThough before any of this can be done, determine how you are going to get this data.

I'm still confused by what you want the array to be. Do you want the entire string in one array element, or each line in an element, or each character in it's own element? What are you trying to do? If all you're trying to do is check if the string contains a zero there is a much easier way.

hi! i want each character in an array, then it will check each character of the string if it contains zero. thanks

OK, you can break the string up into an array of characters like this:chars = file_text.split("");You can check if a zero is in the string like this:zero_exists = (file_text.indexOf("0") != -1);The zero_exists variable will be true if a 0 is in file_text, or false otherwise.

ok, how about i will check the array each character, then if i found zero in that location it will do something?For example, i have the content of text file below:1110111if(zero_exists){ ....do something here.. and tell the exact location of zero in text file or if the output is in the table form, the zero is found in column 4 and it will change the bgcolor of that cell..? thanks...}

If you have an array, you can iterate through the elements using a for loop:

chars = file_text.split("");for(var i = 0; i < chars.length; i++){	if(chars[i] == "0")	{		alert(i + " is a zero!");	}}

Your text field has two delimeters: "" and "\n" (or "\n\r"). You may want to split the text into lines by splitting on the newline character and then, for each line, split up the line into characters on the empty string ("").
