Pass Javascript Alert a Value
I'm looking for a simple javascscript alert box. I need to be able to pass the alert box a string of text.
Is something like this possible? My syntax is probably wrong.
<html>
<head>
<script type="text/javascript">
function show_alert()
{
alert(my_string_here);
}
</script>
</head>
<body>

<input type="button" onclick="show_alert()" value="Show alert box" string="alert for system number 2" />
</body>
</html>
<html>
<head>
<script type="text/javascript">
function show_alert(my_string)
{
alert(my_string);
}
</script>
</head>
<body>
<input type="button" onclick="show_alert('This will alert!')" value="Show alert box" string="alert for system number 2" />
</body>
</html>
This makes no sense thou. Better solution:
<html>
<head>
</head>
<body>
<input type="button" onclick="alert('Doh!')" value="Show alert box" string="alert for system number 2" />
</body>
</html>
Try:
<input type="button" onclick="alert('alert for system number 2');" value="Show alert box" />
What are you trying to do? alert('Your string here') should do the trick if you really need an alert.
Yes you can
function testAlert(val){alert(val);}
Yes this is possible
<script type="text/javascript">
function testAlert(val){alert(val);}
</script>
<input type=text onclick='testAlert(this.string)' string="something" value="clik here">
alert("alert for system number 2");
加载中,请稍侯......
