jQuery passing element ID into jquery statement?

Question

I\'d like to pass the ID of an element into a function which then calls jQuery. However, I\'m stumped as to how to actually take the ID variable and concatenate it with othe

Answer 1

I think you'd get better reuse if you passed an entire selector as a parameter, remembering that jQuery implicitly iterates over all matched elements. For a rudimentary example:

function hideImageDescendants(selector){
    $(selector).find("img").hide();
}

Answer 2

When button is click then it get the button id which I later use to get it's field data, use + operator to dynamic change id

$('.btnsave').click(function() 
  {
      btnvalue = $(this).val();
      //alert(btnvalue);
      adjust_value = $('#adjust_value'+btnvalue).val();
      ado = $('#ado'+btnvalue).val();
      amount =  $('#amount'+btnvalue).val();
      description = $('#description'+btnvalue).val();
      //alert(adjust_value+ado+amount+description);
      
  })

Answer 3

Just do this--

myfunction('obj')
function myfunction(obj){
$('#'+obj+' img').show();
}

Or, even

myfunction($('#2 img a'));

myfunction(jqobj){
jqobj.show();
}

Answer 4

myFunction("#myObject");

function myFunction(IDofObject){

    $(IDofObject+" img").doSomething...

}

Try that.

Answer 5

Ugh. one of those '2 seconds after you ask you figure out...' questions:

function myFunction(IDofObject){

    $(IDofObject+" img").doSomething...

}

Answer 6

Don't wrap the parameter in quotes:

function myFunction(IDofObject) {
    $( IDofObject + " img" ).doSomething();
}

Also, you may want to consider adding the hash character inside the function so you can pass it the actual id, not a selector.

myFunction( $('.classSelector :first').attr('id') );

function myFunction(IDofObject) {
    $( "#" + IDofObject + " img" ).doSomething();
}
