Question

I have a JS

function check(obj) {

for( i=0; i<obj.elements.length; i++){
    if(obj.elements[i].type=="checkbox"&&obj.elements[i].checked){
        if(confirm(onSubmitMessage)){
            return true;
        }
        else{
            return false;
        }
    }
}
alert(alertMessage);
return false;
}

It’s called from jsp page like this:

<script src="/TestAppChanged/check.js" type="text/javascript">
    var onSubmitMessage = '"<bean:message key="body.onsubmit.delete"/>"';
    var alertMessage = '"<bean:message key="body.alert.delete"/>"';
</script>
...
<form action="MyAction" method="POST"
onsubmit="return check(this)">

The problem is in that it doesn’t see these glabal variables: onSubmitMessage and alertMessage. I thought that the problem was in the way that these things are set and changed it’s values to usual strings like "qwe" but it didn’t work again. So script in it’s body simply doesn’t see these variables. And the question is how to get them from script?

Answer 1

The <script> tag is used either to load an external file, like <script src="path/to/file.js"></script> or to define JS code inside the tag, like:

<script type="text/javascript">
    // Your JS code.
</script>

You can’t have both on the same tag. Thus, split your code:

<script src="/TestAppChanged/check.js" type="text/javascript"></script>
<script type="text/javascript">
    var onSubmitMessage = '"<bean:message key="body.onsubmit.delete"/>"';
    var alertMessage = '"<bean:message key="body.alert.delete"/>"';
</script>
