I have a string, an array of words to be searched for:
strng = "I have been working here since last six months"
text = ["since", "till", "until"]
result = "since"
I want to search for every word in array, in strng and when any of it is found in the strng, it must be assigned to result. how to do it?
I am using .search() for searching a single word, but how to search for multiple words? please help.
I am a Newbie.
You can either loop over your array of keywords or use a regular expression. The former is simple, the latter is more elegant ;-)
Your regex should be something like "/since|till|until/", but I'm not 100% sure right now. You should research a bit about regexes if you're planning to use them, here's a starter: http://www.w3schools.com/js/js_obj_regexp.asp
EDIT: Just tried it and refreshed my memory. The simplest solution is using .match(), not search(). It's boils down to a one-liner then:
strng.match(/since|till|until/) // returns ["since"]
Using .match() gives you an array with all occurrences of your pattern, in this case the first and only match is the first element of that array.
I think regular expression is the simple solution for that. Use match() instead of search().
if you write it as,
strng = "I have been working here since last six months"
text = /(since)|(till)|(here)/
result= strng.match(text); // result will have an array [since,since,]
correct solution is to write,
result=strng.match(text)[0];
You can loop through each item in text with .search() like this
for (var i=0; i < text.length; i++)
{
if (-1 != strng.search(text[i]))
{
result = text[i];
break;
}
}
Do it like this...
strng = "I have been working here since last six months";
text = ["since", "till", "until"];
results = []; // make result as object
for(var i=0; i<=text.length; i++){
if(strng.indexOf(text[i]) != -1)
results.push(text[i]);
}
To make indexOf work in IE, put this code in your script
if (!Array.prototype.indexOf) {
Array.prototype.indexOf = function(obj, start) {
for (var i = (start || 0), j = this.length; i < j; i++) {
if (this[i] === obj) { return i; }
}
return -1;
};
}
You can do like this:
var result;
for(var x = 0; x < text.length; x++){
if(strng.indexOf(text[x]) > -1){
result = text[x];
break;
}
}
alert(result);
