3. Loops execute a block of code a specified number of times, or while a specified condition is true  In JavaScript, there are two different kind of loops: ◦ for - loops through a block of code a specified number of times ◦ while - loops through a block of code while a specified condition is true 3

4.  Used when you know in advance how many times the script should run.  Often used to cycle through lists or arrays Syntax for (var=startvalue;var<=endvalue;var=var+increment) { code to be executed } Example var fruit = "apples,oranges,bananas".split(","); for (i=0;i<fruit.length;i++) { alert("We have many sweet " + fruit[i] + "!"); } 4

5.  The while loop cycles through a block of code while a specified condition is true.  Used when exact input is unknown Syntax while (var<=endvalue) { code to be executed } Example var name = prompt("What is your name", "Enter your name here"); while (name != "Done") { alert("Very happy to meet you " + name + "!"); var name = prompt("What is your name", "Enter your name here"); } 5

6.  Used to manipulate a stored piece of text.  The Math object includes several mathematical constants and methods. The following example uses the length property of the String object to find the length of a string: var txt="Hello world!"; document.write(txt.length); The following example uses the toUpperCase() method of the String object to convert a string to uppercase letters: var txt="Hello world!"; document.write(txt.toUpperCase()); 6 12 HELLO WORLD!

7. MethodDescription indexOf() Returns the position of the first found occurrence of a specified value in a string lastIndexOf() Returns the position of the last found occurrence of a specified value in a string match() Searches for a match between a regular expression and a string, and returns the matches replace() Searches for a match between a substring (or regular expression) and a string, and replaces the matched substring with a new substring search() Searches for a match between a regular expression and a string, and returns the position of the match slice() Extracts a part of a string and returns a new string split() Splits a string into an array of substrings substr() Extracts the characters from a string, beginning at a specified start position, and through the specified number of character substring() Extracts the characters from a string, between two specified indices toLowerCase() Converts a string to lowercase letters toUpperCase() Converts a string to uppercase letters 7

8.  Each HTML document loaded into a browser window becomes a Document (DOM) object.  The Document object provides access to all HTML elements in a page, from within a script.  JS HTML DOM can be used to retrieve dynamically assigned ids of elements, during test execution  Complete DOM reference: http://www.w3schools.com/jsref/default.asp 8

9.  getElementById() - Accesses the first element with the specified id getElementById()  document.getElementById()  getElementsByName() - all elements with a specified name getElementsByName()  document.getElementsByName()  getElementsByTagName() - Accesses all elements with a specified tagname getElementsByTagName()  document.getElementsByTagName() 9

11.  id - Returns the id of an element id  var x = document.getElementsByTagName(“div”);  var element_id = x[0].id;  nodeType - Returns the type of the element nodeType  var x = document.getElementsByTagName(“input”);  var element_type = x[0].nodeType;  tagName - Returns the tagname of an element as a string (in uppercase) tagName  var x = document.getElementsByName(“firstName”);  var element_tag = x[0].tagName; 11

12.  hasChildNodes() - Returns whether an element has any child elements hasChildNodes()  var x = document.getElementById(“admin”);  var isParent = x.hasChildNodes();  toString() - Converts an element to a string toString()  var x = document.getElementById(“admin”);  var sub_menues = x.toString();  attributes[] - Returns an array of the attributes of an element attributes[]  var x = document.getElementById(“admin”);  var all_attributes = x.attributes[];  childNodes[] - Returns an array of child nodes for an element childNodes[]  var x = document.getElementById(“admin”);  var sub_menues = x.childNodes[]; 12
