from HTML send an event plus variable to JS function
I want to send a mouse event and a variable to a JS function from within my html code, i can send the event fine but the proble开发者_StackOverflow社区m is sending the event AND a variable. I have included a stripped down version of what I am trying to do. The browser is chrome. Can anyone offer some advice please ??`
function mouseDown(e,w) {
var ctrlPressed=0;
var evt = navigator.appName=="Netscape" ? e:event;
ctrlPressed =evt.ctrlKey;
self.status="" +"ctrlKey=" +ctrlPressed
if (ctrlPressed)
alert ("Mouse clicked with Ctrl/n and the variable is " + w )
return true;
}
</script>
<body>
<table border = "1" >
<tr>
<td onmousedown="mouseDown(e,\"variable\")"> Link 1 </td>
<td> Link 2 </td>
</tr>
</table>
</body>`
Don't use browser detection. Check whether an object exists instead.
var evt = navigator.appName=="Netscape" ? e:event; // wrong
var evt = e ? e : event; // right
var evt = e || event; // also right
Since the event is passed as the 1st argument, you could try
<td onmousedown="mouseDown(arguments[0], 'variable');"> Link 1 </td>
(I have only tested this on Safari, not guarantee to work on other browsers.)
