Preventing user from inserting *
- by user990635
I'm trying to prevent user from inserting * in a textbox.
This is what I was trying to do, but here it only detects * if this is the only inserted character. For example texts like: *, etc.
When allowed characters are mixed with *, then it cannot detect it. For example inputs such as: *hjh, etc..
and maybe how to make it replace only * with "" and not the whole field?
<script type="text/javascript">
function testField(field) {
var regExpr = new RegExp("[^*]");
if(!regExpr.test(field.value)) {
field.value = "";
}
}
</script>
<input type="text" id="searchGamesKeyword" class="searchGamesTextBox"
name="searchGamesKeyword" onblur="testField(this);" />
