alternative For {!$component}

Hello,

I am working with javascript. I need to select A field. My javascript is out side the blocks. so With $component  id have to usw hierarchical id (or Dom tree id). structure like {!component.mypage.mypageblock.myfield}. 
I Can't use something {!component.mypage.mypageblock.myfield} as only id fixed is myfield.
 what is the alternative how can i select field directly?

Hi Abhilash,

If you are using jQuery on your page you can use $("[id$='<Field ID Here>']") css selector.

Let me know if this works

Consider the below example. Hope it will help you.

alert(idValue);
}

<apex:pageblocksection>
<apex:inputField value="{!Account.Name}" onblur="alertMethod(this.id);"/>
</apex:pageblockSection>
</apex:pageblock>
</apex:page>


Let me know if you need more help.

Hi Manoj,

I am Using Javascript. so It would be better if can use something with document.getElementById().

I dont want to change whole code to jQuery. although I will if there will be no solution

Hi Abilash,

Whatever i have mentioned uses javascript. Inside the method you can use
function alertMethod(idValue){
document.getElementById(idValue);
}

Hi Manoj,
 but I have to address some other filelds. not the one binded with event. so this will not be helpful. I guess.
<apex:page>
<script>
 function alertMethod(idValue){
alert(idValue);
}
</script>
<apex:pageblock>
<apex:pageblocksection>
<apex:inputField value="{!Account.Name}" onblur="alertMethod(this.id);"/>
<apex:inputField value="{!Account.accountnumber}"  id="accN"/>
</apex:pageblockSection>
</apex:pageblock>
</apex:page>


How will you operate for accN ?

<apex:inputField value="{!Account.Name}" onblur="alertMethod(this.id);"/>
<apex:inputField value="{!Account.accountnumber}"  id="accN" onblur="alertMethod(this.id)"/>// this will work and will get the id
</apex:pageblockSection>
</apex:pageblock>
</apex:page>

You are using onblur ib accN too.  How will you get these two id, if event was happening some where else.

What if on  click of a button I need to set those field to some values

Okay Abnilash, 

Now I got your question. Sorry we went in a wrong way.
If you dont want to use {!$Component.IDValue}


We can use the same onBlur Method to debug the IDValue and then we can use it in our button

for Example
<apex:page>
<script>
 function alertMethod(){
alert(document.getElementById('Pass that id that you got in the previous code'));
}

function findId(idValue){

alert(idValue);
}


</script>
<apex:pageblock>
<apex:pageblocksection>
<apex:inputField value="{!Account.Name}" onblur="alertMethod(this.id);"/>
<apex:inputField value="{!Account.accountnumber}"  id="accN" onblur="FindID(this.id)"/>// this will work and will get the id
</apex:pageblockSection>
<apex:commandButton value="Save" onclick="alertMethod"/>
</apex:pageblock>
</apex:page>

You can also use F12 and check the id of the required Input text or field.



Thanks

Hi Abhilesh,

You can uses document.getElementsByClassName to get the element you need matching the class name. Check the sample code.
  
<apex:page >
  <script>
      function getAllInputValues(){
          var allInputs = document.getElementsByClassName('input-fld');
          console.log(allInputs);
      }
  </script>
  <apex:form >
      <apex:pageBlock >
          <apex:inputText id="id1" styleClass="input-fld"/>
          <apex:inputText id="id2" styleClass="input-fld"/>
          <input type="button" value="click me!" onclick="getAllInputValues()"/>
      </apex:pageBlock>
  </apex:form>
</apex:page>
Let me knoe if this works
