(Apex) Pop a message when input done and click save

<apex:page controller="MyController" sidebar="false">
<apex:form >
    <apex:inputText size="36" value="{!Str}"/>
    <apex:commandButton onClick="alert('{!Str}');" value="Alert"/>
</apex:form>

The code is just to pop out an alert window to display the input. However, it seems not a possible to do so with Salesforce apex since it's a server-side language. Am I correct ?

Solution

  • Fou new value of str you nead select it by javaScript or jQuery.

    apex:inputText styleClass="str" value="{!Str}"

    'alert($('.str').value())'
