Links text based browser

Copy linkTweet thisAlerts:

Could anyone point me to some help on using Javascript specifically for the Links text based browser. We use this browser on our handheld scanners. Need help specifically for trapping function keys, cursor control, and the [Killscript] button in the alert box.

Thanks. Any help at all appreciated.

It's running the Javascript - it's just that some parts are working and some parts aren't. I'm using code built for IE, so I wonder if the browser is interpreting it differently, just as Netscape would.

thanks

@Naomi_BellauthorAug 11.2004 — Hi, Neil. Here's the code:

This code checks an input field. The alert box pops up, but with an extra [Killscript] button that lets the user skip out of the checking function.

if (document.Information.Pcs.value == '') {

alert("Pcs?");

document.Information.Pcs.focus();

document.Information.Pcs.select();

return false;

}

This code places the cursor in the input fields. Works in IE, not in Links.

function placeFocus() {

if (document.forms.length > 0) {

var field = document.forms[0];

for (i = 0; i < field.length; i++) {

if ((field.elements[i].type == "text") ||

(field.elements[i].type == "textarea") ||

(field.elements[i].type.toString().charAt(0) == "s")) {

document.forms[0].elements[i].focus();

break;

}

}

}

}



This code traps a function key. Works fine in IE, ignored by Links.

document.onkeydown = function(){

if(window.event && window.event.keyCode == 116)

{ // Capture and remap F5

window.event.keyCode = 505;

}



if(window.event && window.event.keyCode == 505)

{ // New action for F5

alert('F5 key was pressed');

return false;

}

}



If I turn on an option in the browser, it will give warning msgs about Javascript syntax, but none of it makes any sense. And the code works in IE.



Thanks for your help.

@neil9999Aug 12.2004 — Does Links even support form fields? Please could you post the code for the whole page, including any (X)HTML, and any warnings/error messages.

What option?

Do you mean like those self-service scanners you get in Supermarkets? If so, it might be better to get a custom-made program for it.

Aaah - so Links and Lynx (http://lynx.browser.org/) must be two different text-based browsers with similar names.

How confusing for the users!
