Hi,
I have been trying to validate an input field with javascript using onmousedown="function();return false;" inside a commandbutton.
<h:commandbutton onmousedown="myfunc();return false;" action="mybean.x"/>
This works fine in internet explorer, but in firefox, the action method is still called, even if javascript validation fails.
anyone can help?
Wrong, IE is failing hardly. Remove the "return false" and you'll see that the form is even not submitted.
Onmousedown/up events aren't intented for the actions you expected. Use onclick instead. And let the function return false or true and don't hardcode "return false;" in the onclick.
Tried that.
It works in IE, but not in firefox (action method is called after clicking ok on alert)
My code is as follows.
validate(){
if(condition){
return false;
}
}
<body>
<f:view>
<h:form>
<h:commandButton onclick="return validate();" action="myBean.x"/>
</h:form>
</f:view>
</body>
Then your JavaScript is simply bad. Use the Web Developer Toolbar extension to check for any JS errors and/or use the Venkman JavaScript Debugger extension to debug the JS.
To prove that this should just work in FF: here is a simple example to try it out yourself:
<h:form>
<h:commandButton value="false" onclick="return false;" action="#{myBean.action}" />
<h:commandButton value="true" onclick="return true;" action="#{myBean.action}" />
</h:form>
MyBeanpublic void action() {
System.out.println("booh!");
}
