NEed Help, Aqi calculator change javascript to JAva Gui.?

**Bli** · February 13th, 2013, 11:25 AM

i need help for interpreting this javascript to javacode. this script is about AQI calculator.<br> the code in java srcript, does someone can help me immediately. here is the link and so the code too :,br>

 if (cmbPol.getItemAt(index) == "3");

You should use the equals() method for comparing Strings, not the == operator

Can you explain your problem with the getSelectedIndex() method?

The posted code has many compiler errors. You should fix those before writing any more new code.

**Bli** · February 14th, 2013, 04:50 PM

firstly i try to interpreting this javascript step by step.from this scriptbelow, when i click the item list of JComboBox in TextUnit will appear the Units.

if (document.form.pollutant.selectedIndex == '1' || document.form.pollutant.selectedIndex == '2')
{
	document.form.txtunit.value="ug/m3";	
}
else if (document.form.pollutant.selectedIndex == '3')
{
	document.form.txtunit.value="ppm";	
}
else if (document.form.pollutant.selectedIndex == '4' || document.form.pollutant.selectedIndex == '5' || document.form.pollutant.selectedIndex == '6' || form.pollutant.selectedIndex == '7' || form.pollutant.selectedIndex == '8')
{
	document.form.txtunit.value="ppb";	
}
return true;
}

im using netbeans, i apologize for the bugs.i try to use getSelectedIndex then the unit will change and not appear the item. and this my code, but it dosnt work...

int index = cmbPol.getSelectedIndex();
                String str;
                if (cmbPol.getItemAt(index).equals(3)){
                textAqi.setText("You Selected : ");}// +      
 
                if(cmbPol.getItemAt(index).equals(2)){
                textAqi.setText("sagertrh ");
                }
                else{textAqi.setText("sgg ");}

thank you for reply

First get the code you posted to compile without errors and execute and show a GUI window.
When that is done, THEN worry about adding more code. Don't add any more code until the current code compiles and executes without errors.

The posted code still has compiler errors that need to be fixed.

I see you have add the listener method now. It was not in post#9

Now you can start adding the code you were talking about.

**Bli** · February 14th, 2013, 06:24 PM

oke. you mean about my code problem? in that code, getselectedindex doesnt work. do you have any explanation why or some example? what is the right statements for my code?

**Norm** · February 14th, 2013, 06:37 PM

Add some println statements that print out the values that are returned by the methods so you can see what the computer sees when it executes the if statement.

**Bli** · February 14th, 2013, 06:55 PM

would you explain more specifically sir?

**Norm** · February 14th, 2013, 07:25 PM

Print out what is returned by these methods:
cmbPol.getSelectedIndex()
cmbPol.getItemAt(index)

**Bli** · February 14th, 2013, 10:31 PM

if i print out the returned from its method then the number of index will displayed. i mean, how to replace selected index that i choose with other statements? in this case i give each index of item with unit item, e.g. when i click the firs polutan then unit become mg,second pollutant unit become kg, etc.

**Bli** · February 15th, 2013, 01:43 AM

i've already add this code, and itswork, but i supposed to get more simple codes using selectedindex. for a while this is work. now im going continue to other function method.i hope you can help me. thank you mr.Norm.

cmbPol = new JComboBox(listpolutan);
        cmbPol.setLocation(80, 10);
        cmbPol.setSize(cmbPol.getPreferredSize());
        cmbPol.addActionListener(new ActionListener() { 
        public void actionPerformed(ActionEvent e) {
 
                if(cmbPol.getSelectedItem().equals("PM2.5 - Particulate &lt;2.5 microns (24hr avg)")){
                textUnit.setText("ug/m3");}
                if(cmbPol.getSelectedItem().equals("PM10 - Particulate &lt;10 microns (24hr avg)")){
                textUnit.setText("ug/m3");}
                if(cmbPol.getSelectedItem().equals("CO - Carbon Monoxide (8hr avg)")){
                textUnit.setText("ppm");}
                if(cmbPol.getSelectedItem().equals("SO2 - Sulfur Dioxide (1hr avg)")){
                textUnit.setText("ppb");}
                if(cmbPol.getSelectedItem().equals("SO2 - Sulfur Dioxide (24hr avg)")){
                textUnit.setText("ppb");}
                if(cmbPol.getSelectedItem().equals("O3 - Ozone (8hr avg)")){
                textUnit.setText("ppb");}
                if(cmbPol.getSelectedItem().equals("O3 - Ozone (1hr avg)")){
                textUnit.setText("ppb");}
                if(cmbPol.getSelectedItem().equals("NO2 - Nitrogen Dioxide (1hr avg)")){
                textUnit.setText("ppb");}
 
                     }
               });

Instead of matching against the full String from the combobox, could you just just the index value?
A problem when matching full Strings is they can be mistyped and not be the same String.
