Define apex:variable in apex:inputText

Question

I'm trying to pass parameters while using immediate=true. (actionRegion is not an option)

Since this won't work:

    <apex:inputText value="{!searchValue}" />
    <apex:commandButton value="Search" action="{!doSearch}" immediate="true"/>

I tried to create a variable and use it like this:

1: <apex:variable var="input" value="" />
2: <apex:inputText value="{!input}"/>
3: <apex:commandButton value="Search" action="{!doSearch}" immediate="true">
4:      <apex:param name="value" assignTo="{!searchValue}" value="{!input}" />
5: </apex:commandButton>

But in line 2 it tells me

Save error: Unknown property 'input'

Any idea if there is a way to define this variable with any kind of user input?

Last option would be some hacky JS like: onblur="setApexVar()" any experience with this?

Answer 1

you can try something like

    <apex:variable var="input" value="" />
     <apex:inputText value="{!input}" styleclass="textCls"/>
     <apex:commandButton value="Search" onclick="passValue()" rerender="none"/>
      <apex:actionfunction action="{!doSearch}" immediate="true" />
          <apex:param name="value" assignTo="{!searchValue}"/>
     </apex:actionfunction>

<script>
   function passValue()
   {
        var val= document.getElementsByClassName('textCls')[0].value;
       actfun(val);

    }
<script>

Using this actionfunction you can pass value to controller.

Update: I am not sure about actionfunction but you can remove one script method.

     <apex:inputText styleclass="textCls"/>
     <apex:commandButton value="Search" onclick="actfun(document.getElementsByClassName('textCls')[0].value);" rerender="none"/>
      <apex:actionfunction action="{!doSearch}" immediate="true" />
          <apex:param name="value" assignTo="{!searchValue}"/>
     </apex:actionfunction>
