I have created pdf map pages from ESRI's ArcMap that contain multiple layers. I have created pushbuttons (5 formfield checkboxs) on the legend items. I want to attach javascript code (which I already have) to the each button which will toggle the visibilityof the legend layer (OCG) item. This allows users to quickly toggle these 5 OCGs on and off. Easier than using the layer menu because the script also toggles the labels for the OCG.

I have 476 map pages to update with this code. I already have the code for entering other fields in place on these pages but I am stuck with the javascript.

I have gotton to where I am supposed to enter the javascript in the function (FormFieldJavaScriptAction for example). My code is multiline. How do I put it in this or other functions? Can I enter a reference to a text file that has the code so that it loads the file and runs the script when clicked? Do I have to somehow include the code in the pdf? If so, how? Basic code examples would be a great help.

Thanks in advance.

I have already checked those out, but they don't answer my basic question.

For example, when entering the function FormFieldJavaScriptAction it calls for "Javascript as String" as a parameter. One of the scripts I want to run when this button is pushed is:

var docOCGs = this.getOCGs();
for (var x=0; x < docOCGs.length; x++)
{
if(docOCGs[x].name == "City")
{
docOCGs[x].state = !docOCGs[x].state;
}
if(docOCGs[x].name == "City - Default")
{
docOCGs[x].state = !docOCGs[x].state;
}
}

This toggles the City OCG and its label OCG. I can't enter this as the parameter because of the length and multilines. How do I actually enter the above javascript into the pdf so that I can use this function to run it? I can do it from a pdf editor one file at a time, but that isn't practical.

You code can easily be added as a string.

string s = "var docOCGs = this.getOCGs();\n" +

"for (var x=0; x < docOCGs.length; x++)\n" +
{\n" +
if(docOCGs[x].name == "City") \n" +
{\n" +
docOCGs[x].state = !docOCGs[x].state;\n" +
}\n" +
if(docOCGs[x].name == "City - Default")\n" +
{\n" +
docOCGs[x].state = !docOCGs[x].state;\n" +
}\n" +
} \n";

Just pass this string to the FormFieldJavaScriptAction. You could even put all of the code on one line and it would run fine.

Thank you for the idea and response.

I had just stumbled upon that approach yesterday and it does work. It does seem clumsy and that there should be an easier way, but it works.

I may attempt to try reading the scripts from a file as a string just for the heck of it. This would allow for much easier editing of the java and longer scripts.

Thanks again.

Loading it as a string from a file would be the easiest and most manageable approach.
