Question

can i give more than one parameter to the split function in javascript to remove more than one thing and put it into array? for expamle:

 var str= "This is Javascript String Split Function example ";

 var wordArray=str.split(" ");

this will give me each word separately

in addition of this result, i want to remove “is” and “this” from the array, so can i put in the split function many parameter to remove from the beginning ” “ & “is” & “this” ? or should i use another function than split() ?

Answer 1

there are many ways to achieve what you want. Basically you want to remove is and this

so either you can do this:

a. If words you want to remove are always the first and the second one then

 var filteredArray = str.split(" ").splice(2);

b. If words you want to remove can be anywhere in the string

var  filteredArray = str.replace(/this|is/g, function(w){

        switch(w){
           case 'this':
                 return '' ;

              case 'is':
                   return '';
          }

    }).trim().split(' ');

c. There is one more lame way to do this.

var str= "This is Javascript String Split Function example ";
var parts = str.split(' ');
var clean = [];
for (var i = 0; i < parts.length; i++) {
   var part = parts[i];
   if (part !== "This" && part !=="is")
      clean.push(part);
}

d. using simple regex to replace multiple words

var str= "This is Javascript String Split Function example ";
   var words = ['This', 'is'];
   var text = str.replace(new RegExp('(' + words.join('|') + ')', 'g'), '').split(' '); 

based on your need you can go for any one of them.
