Multiples Find Replaces with TRY CATCH errors in alert and console

[manuelb27477138]

Hello!

In my script I find and replaces many words:

    replaceTextUsingFIND ("Article 1.", "Article ONE"); 
    replaceTextUsingFIND ("Article 2.", "Article TWO"); 
    replaceTextUsingFIND ("Article 3.", "Article THREE"); 
    replaceTextUsingFIND ("Article 4.", "Article FOUR");
    function replaceTextUsingFIND (input, output)  
    {  
        app.findTextPreferences = app.changeTextPreferences = NothingEnum.nothing;  
        app.findTextPreferences.findWhat = input;  
        app.changeTextPreferences.changeTo = output;  
        app.activeDocument.changeText();  
        app.findTextPreferences = app.changeTextPreferences = NothingEnum.nothing;   
}

This is my document:

In this case, the words Article 2. and Article 4. do not exist, then I need to get one alert per each word.

Is possible get the errors by alert and in the Javascript console? I try with try/catch but didn't work 

Thanks for help me!

HI,

It is not possible to get errors as such, as no error is thrown if the find doesn't find anything, but you can catch that the find didn't find anything.

if you change the following line

app.activeDocument.changeText();

to

var changedResults = app.activeDocument.changeText();

Then you can check the length of changedResults to see if anything was changed something like

if ( changedResults === 0)
{
     // I have put it into a alert, but you could put it to the console.
     alert ( "No results for " + input);
}

Hpoe this helps

Hi Malcolm!

I needed a change in the if conditional this === to ==

And now is working!

Here is the final Script:

    replaceTextUsingFIND ("Article 1.", "Article ONE");    
    replaceTextUsingFIND ("Article 2.", "Article TWO");  
    replaceTextUsingFIND ("Article 3.", "Article THREE");  
    replaceTextUsingFIND ("Article 4.", "Article FOUR"); 
    function replaceTextUsingFIND (input, output)   
    {   
        app.findTextPreferences = app.changeTextPreferences = NothingEnum.nothing;   
        app.findTextPreferences.findWhat = input;   
        app.changeTextPreferences.changeTo = output;   
        var changedResults = app.activeDocument.changeText();   
        app.findTextPreferences = app.changeTextPreferences = NothingEnum.nothing;    
        if ( changedResults == 0)  {
            alert ( "No results for " + input);
        } 
}

Thanks so much!

Hi,

The === matches type as well as value, == just matches value.

I think this is because I missed out the .length inside the if, so it should look like this

if ( changedResults.length === 0)

but as long as it is working which is the main thing.

Regards
