JavaScript : Problem with document.write()?
Im new to JavaScript and I have traced problems I have been having to this. Can you tell me what Im doing wrong.
Works
if( document.myform.box1.checked ){
document.write( "true<br>" );
} else {
document.write( "false<br>" );
}
Prints
true
Works
if( document.myform.box2.checked ){
document.write( "true<br>" );
} else {
document.write( "false<br>" );
}
Prints
true
Works
if(true){
document.write( "true<br>" );
}
else{
document.write( "false<br>" );
}
if(false){
document.write( "true<br>" );
}
else{
document.write( "false<br>" );
}
Prints
true
false
Doesnt Work
if( document.myform.box1.checked ){
document.write( "true<br>" );
} else {
document.write( "false<br>" );
}
if( document.myform.box2.checked ){
document.write( "true<br>" );
} else {
document.write( "false<br>" );
}
Prints
true
The first 3 print what you would expect, the last only prints the first line. It wont print both true/false messages. Any ideas why?
2 AnswersProgramming & Design1 decade agoJavaScript & DOM : Telling if a checkbox has been checked?
Ive never written anything in javascript before, and I am having some difficulties figuring the DOM out. What I want to do is have a form with checkboxes, when a user hits a submit button, whatever checkboxes were selected will display a different table. Right now Im having trouble telling if a checkbox is checked. I havent really found any tutorials out there to describe this well. In a nutshell this is what I have.
<head>
function GetResults(form) {
var d = document;
d.write("<html><body>");
if( form.box["1"].checked ){ // what goes here?
d.write("hi<br>");
}
d.write("</body></html>");
}
</head><body><form>
<input type="checkbox" name="box" value="1" />
<input type="checkbox" name="box" value="2" />
<input type="button" value="Get Results" onclick="GetResults( this.form );" />
</form></body></html>
Any suggestions would be helpful, I'm sure I am doing many things wrong.

I am working on a webpage in .Net.
I would like to have when I mouse over a table cell for a small pop-up window with a message to appear.
To see an example of what I would like to do - http://www.tvguide.com/listings/default.aspx
Any Ideas on how this is done?
Hopefully it doesnt matter but the tables are built using Anthem.net for AJAX support.
2 AnswersProgramming & Design1 decade agoC Programming - Reading input from STDIN - need help.?
I need to write a program in pure C. Coming from a C++/Java background I am slightly confused.
I would like to read in a float value from STDIN. I see there are functions like read(), scanf().... that will let you read in char[], but nothing to read in something else.
So how can a read in a float, or how would I convert a char[] to a float.
5 AnswersProgramming & Design1 decade agoC Passing a 3-D array of char strings to a function?
So I have a 3-D array of char strings -
char* val[256][256][256];
I need to pass a reference of this to a function, how do I do this?
If it was a single array I can pass it as follows
char* val[256]
func(val);
....
void func(char** a){}
However
void func(char**** a){}
doesnt work.
Any suggestions?
