Hi 

i have one command button "save" which return the apex message after the operation. i need to check for the particular message return.i.e

suppose below is my save button

<apex:pageMessages id="pmsg"/>

  <apex:commandButton value="Save"   action="{!Save}" />

which return the apex message. i need that if the message is" not enough value exist"

thn i need the confirmation box 

"are u sure want to create act thn click the ok "

if it click ok thn it redirect the action save again with the parameters as i did

<apex:actionFunction name="CallApexMethod" action="{!Save}">
<apex:param name="key" value="val"/>
</apex:actionFunction>

My Logic:

<apex:form id="form" >
<apex:pageBlock title="FF Info" id="pb">

<apex:pageMessages id="pmsg"/>

 <apex:commandButton value="Save"  onclick="CallApexMethod1();" oncomplete="Redirect();" />

 <apex:actionFunction name="CallApexMethod1" action="{!Save}"/>
<apex:actionFunction name="CallApexMethod" action="{!Save}">
<apex:param name="key" value="val"/>
</apex:actionFunction>

<script>


function Test()
{
alert("1");
CallApexMethod1();


}
function Redirect()
{
alert("2");

var msgval= document.getElementById("{!$Component.form.pb.pmsg}").innerText;
alert(msgval);
if(msgval =='Not enough miles in account')
{
if (confirm('There are not enough miles in that account. Are you sure you want to continue?'))
{
alert("3");
CallApexMethod() ;
}
}
alert("4");
}


</script>

</apex:form>

</apex:page>

But it not work. also the message is not compare.

In Nutshell :I have one button save on click it and it hit the http and i gt msg which i  print in  apex message. suppose i gt mesage "not enough"  thn i not save the data. but now i need that if  this msg comes a confrimation box will display if it click ok it saves othervwse not
