Snippet:
片段：
var text = 'Be an excellent person';
//Split the string by spaces and convert into array
text = text.split(" ");
// Remove the empty elements from the array
text = text.filter(function(item){return item;});
// Join the array with delimeter space
text = text.join(" ");
// Final result testing
alert(text);
