Javascript Operators


Operators

Normally operators are same in javascript like any language.
Lets consider an example.

var p=5 ;
var q =10;
var z;
z = p+q;

var x;
x=5+5;

o/p : 10

x="5"+"5";

o/p : 55

x=5+"5";

o/p : 55

x="5"+5;

o/p : 55

...

When you want to concat two strings at that time you have to use + sign
For example :

var str = "Welcome" ;
var str1 = "To javascript";

var final ;
final = str + str1 ;

o/p : WelcomeTO javascript.

In above output it doesn't contain space between Welcome and To..
If you want to do that at that time you have to write

final = str + " " + str1;
o/p : Welcome TO javascript.

Number Format In Javascript

Number.toFixed() :                                 Formats any number for "x" number of trailing decimals.

Use of indexOf and charAt in javascript

indexOf(): The indexOf() method returns the position of the first occurrence of a specified value in a string.

Find extension of file in Php

In our scripting sometimes we need to upload such documents , at that time there should be a validation for proper file. For example in your system suppose there is a field for image upload , that is obvious in that field only image formats are allowed (jpg,jpeg,png,gif etc.). At that time you have to give a validation on that field. In Php to find the extension and validation here is your code :  <?php                     $image = $_FILES["file"]["name"];    // to fetch the file name             $n1=strripos($image,".");                     // to find the last position of "."             $v1 =substr($image,$n1);                  ...
