How do I find the value of a SELECT element?
Apr 17th, 2000 16:04
Martin Honnen,




NN6 and IE4+ provide a
value
property for SELECT elements thus
document.formName.selectName.value
is sufficient with these browsers. For other browsers and cross browser
code use
var select = document.formName.selectName;
var value = select.options[select.selectedIndex].value

__________________________________
[select name='navi' onChange="go()">
function go()
{
box = document.forms[0].navi;
destination = box.options[box.selectedIndex].value;
if (destination) location.href = destination;
}

Usage
Want to try it out? Here's how.

Step 1
Place this code between the tags in your webpage.



Step2
This is example html you can use, this goes inside your html body.

Try these: show a1
show a2
show a3
show 'thiscanbeanything'

Classes

if it is a class.


compared to if it is an id.

J = InStr(CODE2, "## " + "##") : CODE2 = Left(CODE2, J - 1)
For J = 0 To TMPA.Count - 1
If InStr(CODE2, "##" + TMPA(J) + "##") = 0 Then NotFound = True : CODE2 = CODE2 + "##" + TMPA(J) + "##" + vbCR
Next
CODE2 = CODE2 + "## " + "##" + vbCR
If NotFound = True Then My.Computer.FileSystem.WriteAllText(Tree2 + Filename + "Code.txx", CODE2, append:=False)

indexOf:
var ss = "a string index of test ";
var result = ss.indexOf("ri");

Replace Function: Global Regular Expression
By enabling the global property of our regular expression, we can go from replacing one match at a time to replacing all matches at once. To enable the global property, just put a "g" at the end of the regular expression.

replace:

Display:
Old string = Hello username! I hope you enjoy your stay username.
New string = Hello Chuck! I hope you enjoy your stay Chuck.

substring:

The output of the code above will be: lo w

Question: How do I convert numbers to strings in JavaScript?

Answer: The simplest way to convert any variable to a string is to add an empty string to that variable (i.e. concatenate it with an empty string ''), for example:


a = a+'' // This converts a to string
b += '' // This converts b to string

5.41 + '' // Result: the string '5.41'
Math.PI + '' // Result: the string '3.141592653589793'
