say i had the string text = "this is a long string i cant display" i want to trim it down to 10 characters but if it doesnt end with a space finish the word i don't want the string variable to look like this "this is a long string i cant dis" i want it to finish the word until a space occurs.
If I understand correctly, you want to shorten a string to a certain length (e.g. shorten
"The quick brown fox jumps over the lazy dog" to, say, 6 characters without cutting off any word).
If this is the case, you can try something like the following:
var yourString = "The quick brown fox jumps over the lazy dog"; //replace with your string. var maxLength = 6 // maximum number of characters to extract //trim the string to the maximum length var trimmedString = yourString.substr(0, maxLength); //re-trim if we are in the middle of a word trimmedString = trimmedString.substr(0, Math.min(trimmedString.length, trimmedString.lastIndexOf(" ")))
