Question

i want the result as

Name: John
Employee Id: 2
Salary: 8000ドル
Address: London

is it possible with split() function in javascript?

Answer 1

You can do it with String.split() but in this case it's simpler to use String.replace():

var description="Name:John;EmployeeID:2;Salary:8000ドル;Address:London";
description = description.replace(/;/g, '\n').replace(/:/g, ': ');
/*
"Name: John
EmployeeID: 2
Salary: 8000ドル
Address: London"
*/

Answer 2

If you want the result as an object, try:

var f = function (str) {
 var x = {}, key2label = { EmployeeID: 'Employee Id' };
 str.replace(/(.+?):(.+?)(;|$)/g, function (match, key, value) {
 key = key2label[key] || key;
 x[key] = value;
 });
 return x;
};

If a simple string is needed, but you still need to replace keys:

var f2 = function (str) {
 var key2label = { EmployeeID: 'Employee Id' };
 return str.replace(/(.+?):(.+?)(;|$)/g, function (match, key, value, semi) {
 key = key2label[key] || key;
 return key + ': ' + value + (semi ? '\n' : '');
 });
};

If you really didn't mean to replace keys, this will do it:

var f3 = function (str) {
 return str.split(':').join(': ').split(';').join('\n');
};

Answer 3

With this statement:

var arrDescription = description.split(";");

you will get an array with all the values. For more info on split check the following link.

you can even join them afterwards :

printf(arrDescription.join(" "));

For more info on join check the following link.

• Saloni: how can i find a substring from arrDescription
• JMax: @Saloni: are you trying to find an item in an array ? --> stackoverflow.com/questions/143847/… or stackoverflow.com/questions/237104/javascript-array-containsobj
• Saloni: i have only substring not the complete string
• JMax: if i understand well, you want to do a search in your array with substring only. you could do a loop on your array but there might be a more efficient way so i advise you to ask another question so that javascript gurus will provide you with the best answers

Answer 4

You can probable try like this to display.

 var description="Name:John;EmployeeID:2;Salary:8000ドル;Address:London";
 var arr=new Array();
 arr=description.split(";"); 
 for(var i=0;i<arr.length;i++)
 document.writeln("<h4>"+arr[i]+"</h4>"); 

• Saloni: if i have description in textBox then how can i use split function.
• Srikanth Venkatesh: You can get the description from textBox using document.getElementById("textBoxId").value

Answer 5

Yes.

You first should split on the semicolon ;. Loop through those results, and split each result on each colon :.

You will have to build the result by hand.

Answer 6

var description="Name:John;EmployeeID:2;Salary:8000ドル;Address:London"; var splitted = description.split(";");

for(var i = 0; i < splitted.length; i++) { document.write(splitted[i] + ""); }
