Personally, I recommend you begin with 'alert' boxes and 'prompt' boxes, then move your way up to variables, until eventually you understand functions, arrays, etc. Then you will be able to create JavaScript masterpieces. You may also want to learn php once you've mastered JavaScript. Simple alert example: Lesson 1: alert boxes alert("This is an alert dialog box."); Body text. Have fun!
What is function parameter or argument in JavaScript?
It is an input to the function. You can use them to apply the same operation to different inputs. You create a function with parameters by putting the parameters in a comma separated list in the parentheses after a function name. For example: function myFunctionWithParameters(parameter1,parameter2,parameter3) { //Code to execute } Within the code, you refer to them as if they were variables that were assigned to the parameter name. For example: function squareNumber(myNumber) { return myNumber*myNumber; } Parameter names follow the same rules as variable names: they cannot start with a number, they cannot have a dot in them, etc. To call a function with parameters, you simply put the values of the parameters within the parentheses. You can also use variable names to refer to the value to pass to the function. For example: var theNumber=10;alert(squareNumber(theNumber)); //Shows alert box displaying 100 Note that parameters can be passed in as any type. For example: function add(a,b) { return a+b; } alert(add(1,2)); //Shows alert box displaying 3 alert(add("foo","bar")); //Shows alert box displaying foobar
