Am currently evaluating PH,(many thanks for a great piece of software,) with a view to using it as the engine in an HTPC/home automation project. Was hoping to use a web browser to control all functionality and therefore my eval time has been spent trying to call macros, functions, and send keystrokes and iR commands directly from a web page.
Have spent many (enjoyable) hours browsing the forums and helps files and, so far have nearly all the functionalitity I require.
Can call macros, send iR commands and send keystrokes, (for controlling media portal, http://mediaportal.sourceforge.net, worth a look,) but, would like to call WSH scripts from an HTML page.
Below is the HTML code I have been using to test functionality.
=====================================================
<html>
<head>
<meta http-equiv="Content-Language" content="en-us">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Test Page</title>
<script language="JavaScript">
//Sendkeys
function f_sk(skeys)
{ document.execsendkeys.sendkeys.value = "ph_rtne(ph_sendkeys('" + skeys + "'))"; document.execsendkeys.submit(); }
//Run a macro
function macro(id)
{ document.execsendkeys.sendkeys.value = "ph_rtne(ph_macro('" + id.toUpperCase() + "'))"; document.execsendkeys.submit(); }
//Send iR remote commands
function f_cc(atype,aid,aparm1,aparm2)
{
document.ccform.type.value = atype;
document.ccform.btnid.value = aid;
document.ccform.parm1.value = aparm1;
document.ccform.parm2.value = aparm2;
document.ccform.submit();
}
</script>
</head>
<form method="post" action="/ph-cgi/ccbutton" name="ccform" target="blankframe">
<input type="hidden" name="type" value="">
<input type="hidden" name="btnid" value="">
<input type="hidden" name="parm1" value="">
<input type="hidden" name="parm2" value="">
<input type="hidden" name="nexturl" value="">
</form>
<form method="post" action="/ph-cgi/execsendkeys" name="execsendkeys" target="blankframe">
<input type="hidden" name="sendkeys">
</form>
<input onclick="f_sk('{downarrow}');" type="button" value="Cursor Down">
<input onclick="macro('UK GOLD');" type="button" value="UK Gold">
<input onclick="f_cc(1,'SKY DIGITAL',15,0);" type="button" value="Favourites">
<input onclick="f_sk('ph_runscript_0("testscript.vbs","vbscript",1,0,"test")');" type="button" value="Call Test Function">
</body>
</html>
=====================================================
As you can see I have buttons for testing but the one I'm having real problems with is the 'Call Test Function' button.
Have tested the script, (a simple 'Hello World' affair,) from within PH successfuly. Can call it from the web page by calling a macro that calls the code, and will continue to do so if it's the only option remaining but would prefer to call it directly from code on the web page. (Have also tried fully pathing the vbs script name)
Many thanks.

Are you saying that the code above does not work? If so, I would guess that your problem would be with the quotes used in you onclick statement. I'm no quote master, but, it has burned me before. Try this...
<input onclick="f_sk('ph_runscript_0(\'testscript.vbs\',\'vbscript\',1,0,\'test\')');" type="button" value="Call Test Function">

Many thanks for taking a look. Aplogies about not being more specific than 'having a problem with'.
When I run the page above it loads into M$IE v6 with no errors, and the 'Call Test Function' button does nothing but no errors are reported either.
Have taken your advice and replaced the " with ' but then IE reports an error when the page is loaded. (Error in the form of ! in yellow triangle at left end of status bar.) It's complaining about 'unterminated string constant' but the line/col reference is at the ' before ph_runscript.
I think I've tried most combinations of ' and ". Have tried ph.runscript & ph_runscript.
Will keep trying.
Seasons greetings
Martyn

Martyn,
Glad to hear you're enjoying PowerHome. Checked out your HTML code and duplicated what you are attempting and found a couple of problems. As Tony stated, the single quotes, double quotes, and embedding them within one another will get you. The proper escaping for the line would be:
<input onclick="f_sk('ph_runscript_0(~~\'testscript.vbs~~\',~~\'vbscript~~\',1,0,~~\'test~~\')');" type="button" value="Call Test Function">
However, this still wont produce the desired result. Within your HTML page, the javascript function f_sk is calling the ph_sendkeys function. When this is properly escaped as in the above line, you will send the ph_runscript function as a "string" to the ph_sendkeys function resulting in keystrokes being produced rather than the function being evaluated.
The ph-cgi function that would be best suited would be the evalformula function. Below, is your HTML page reworked so that the ph_runscript function is called using this method.

{ document.evalformula.formula.value = formula; document.evalformula.submit(); }
//Run a macro

{ document.execsendkeys.sendkeys.value = "ph_rtne(ph_macro('" + id.toUpperCase() + "'))"; document.execsendkeys.submit(); }
//Send iR remote commands
function f_cc(atype,aid,aparm1,aparm2)
{
document.ccform.type.value = atype;
document.ccform.btnid.value = aid;
document.ccform.parm1.value = aparm1;
document.ccform.parm2.value = aparm2;
document.ccform.submit();
}

*************************************************
You would probably want to update the other buttons as well. The execsendkeys function is a holdover from earlier days before the existence of the evalformula function and is pretty much outdated. Since the evalformula function can execute any formula, you can send keystrokes, launch macros, or play IR all from the one function. Below would be an example reworked to use this single function:
**********************************************
<html>
<head>
<meta http-equiv="Content-Language" content="en-us">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>Test Page</title>
<script language="JavaScript">
//Evaluate a formula
function f_formula(formula)
{ document.evalformula.formula.value = formula; document.evalformula.submit(); }
</script>
</head>
<form method="post" action="/ph-cgi/evalformula" name="evalformula" target="blankframe">
<input type="hidden" name="formula">
</form>
<input onclick="f_formula('ph_sendkeys(\'{downarrow}\')');" type="button" value="Cursor Down">
<input onclick="f_formula('ph_macro(\'UK GOLD\')');" type="button" value="UK Gold">
<input onclick="f_formula('ph_ir(\'SKY DIGITAL\',15)');" type="button" value="Favourites">
<input onclick="f_formula('ph_runscript_0(\'testscript.vbs\',\'vbscript\',1,0,\'test\')');" type="button" value="Call Test Function">
</body>
</html>
*********************************************
Hope you had a great holiday and let me know if you have any other questions.
Dave.

Wow! That pretty much covers any function I'll ever need to call from PH.
Many thanks for the examples. Everything explained very clearly.
Thank you
Martyn
