JavaScript - JavaScript Basics
Week 4
These javascript capabilities use the DOM.
1. Write to the Browser Window (pg108)
document.write('<h1> Wlecome to the New and Improved JavaScript Class</h1><p>');
2. Use a variable (pg109)
planet = 17;
document.write('From planet no. ', planet,<br>);
3. Set color (pg112,113)
Note that JS is case Sensitive!
document.color = "orange";
document.write("The background color for this page is " + document.bgColor);
Expand that to include:
.fgColor
.linkColor
4. Document Title (pg116)
name = "Ben";
document.title = "Welcome to" + name + "'s House";
document.write(document.title);
You can also use document.URL or document.referrer
5. Open a New Browser Window (pg120)
window.open ("http://www.yahoo.com", "windowname","width=200, height=300,resizable=yes");
6. Close it (pg 122) Use testpage2.htm
<form>
<input type="button" value ="Close" onclick="window.close();"/>
7. Print the window's contents (pg 124)
<input type="button" value ="Print" onclick="window.print();"/>
8. Move a Window
<form name="form1">
<input type="button" value="Close" onClick="window.close();"/>
<input type="button" value="Print" onClick="window.print();"/>
<p>
horizontal: <input type="text" name="x" value="20"/>
vertical: <input type="text" name="y" value="50"/>
<input type="button" value="moveTo"
onClick="window.moveTo (document.form1.x.value,document.form1.y.value);"/>
</form>
