Check Textframe content

[cmoke73]

Hello!

My „mission“ this time is - shortly explained -  to re-format some tables in a magazine.

For the case one chose one or more Textframes, there is a condition at the beginning of the script:

var myDoc = app.documents[0];  
var myPage = myDoc.pages[0];  
var allSelection = myDoc.selection;
var mySelection = allSelection[0];
var numbSelection = allSelection.length;
for (var i=0; i < numbSelection; i++) {
    if (allSelection.constructor.name != "TextFrame") {
        alert("Bitte wähle einen Textrahmen aus! " + allSelection + " ist KEIN Textrahmen!");
        }
    else if (allSelection.contents.constructor.name != "Table") {
        alert("Der Textrahmen benhaltet keine Tabelle!");
        }
    else {alert("Die Show kann beginnen!")};
    }

All I want to know now is, where is my fault (line 13.)? I want to check if there is a table inside.

else if (allSelection.tables.length > 0) {

   . . .

Though this works only for frames in which a table starts. If the frame contains part of a table that continues from the previous frame you won't be able to test it like this.

Thank you Peter.

But, maybe in my case it has look like:

else if (allSelection.tables.length < 0) { ... ?

than it works, cool!

I didn't didn't see the 'k' in 'Der Textrahmen benhaltet keine Tabelle'.

The difference one single letter can make!

If you don´t mind...

I think it must be the "1" instead the "0", like this:

else if (allSelection.tables.length < 1) { ... ?

What do you think?

[Peter Kahrel]

If a frame does not contain any tables, allSelection.tables.length === 0. So if you want to test whether a frame contains any tables, you use if (allSelection.tables.length > 0).

I don´t know why, but when I try:

if (allSelection.tables.length > 0)...

I get allways (with each text frame selected) the result "Die Show kann beginnen!". Means, there was detected a table, even if there isn´t one.

If I try:

if (allSelection.tables.length < 1)

it works like it should.

If length < 1 does what you want, then that's what you should use.
