I have a datalist which looks like this

<datalist id=properties>

       <option value=property name></option>

       <option value=property></option>

</datalist>

Now I'm using this code to find where values entered by the user is in the list:

var user_property = $('#user_property').val().toLowerCase(); // taken from input type with id user_property

var pro = $('#properties').find(option[value=+user_property.replace(' ','-')+]);

if(pro != null && pro.length > 0)

{

    // run some code

}

else

{

    // show error popup

}

I am getting error in var pro = $('#properties').find(option[value=+user_property.replace(' ','-')+]);

Error code says Syntax error, unrecognized expression: option[value=property name]

How to get rid of this error?
