In french: EditeurHTMLExécuteJS

Executes JavaScript code in an HTML Editor control.

Example

// Get the number of images in the document being edited
HTMLEditorExecuteJS(HTMEDT_MyHTMLEditor, "document.body.images.length", ...

Syntax

HTMLEditorExecuteJS(<HTML Editor control> , <JavaScript code> [, <WLanguage procedure>])

<HTML Editor control>: Control name

Name of the HTML Editor control used.

<JavaScript code>: Character string

JavaScript code to execute.

<WLanguage procedure>: Optional procedure name

WLanguage procedure ("callback") used to find out the result of code execution. This procedure has the following format:

PROCEDURE <Procedure name>(bSuccess is boolean, ReturnValue is string)

This procedure is called once the JavaScript code has been executed. The parameters of this procedure are:
<bSuccess>:
True if the JavaScript code was successfully executed,
False if the execution of JavaScript code generated an error (e.g., error in the JavaScript code). In that case, to get the details of the error, use ErrorInfo.
Remark: A generic error is returned.
<ReturnValue> contains the value of the last expression of the JavaScript code (returned value).

Remarks

The JavaScript code is executed in the context of the document being edited: "document" represents the edited document.
