如何使用选择标签的标题属性删除选择的选项

Question

I want to delete the first option of the selected and I have selected tag id and class but the problem is selected class and id is changing when I open the form of different-2 event.and class "r" of selected tag is using more than one time different-3 drop down of form.

I want to remove the selected option using title attribute of selected tag.

If any other way to resolved this type of problem please share.

<select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*">
  <option value="">Select One </option>
  <option value="Michigan"> Michigan</option>
  <option value="Alabama"> Alabama</option>
  <option value="Alaska"> Alaska</option>
  <option value="Arizona"> Arizona</option>
  <option value="Arkansas"> Arkansas</option>

  <option value="Colorado"> Colorado</option>
  <option value="Connecticut"> Connecticut</option>

  <option value="Florida"> Florida</option>
  <option value="Georgia"> Georgia</option>
</select> 

I want to delete

<option value="">Select One </option>

Answer 1

you can add the hidden attribute:

<option value="" hidden>Select One</option>

this will result in being the default selected value but you can't select it in the dropdown

Example:

 <select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*"> <option value="" hidden>Select One</option> <option value="Michigan">Michigan</option> <option value="Alabama">Alabama</option> <option value="Alaska">Alaska</option> <option value="Arizona">Arizona</option> <option value="Arkansas">Arkansas</option> <option value="California">California</option> <option value="Colorado">Colorado</option> <option value="Connecticut">Connecticut</option> <option value="Delaware">Delaware</option> <option value="Florida">Florida</option> <option value="Georgia">Georgia</option> </select> 

The hidden attribute can also be used to keep a user from seeing an element until some other condition has been met (like selecting a checkbox, etc.).

The hidden attribute is new in HTML5.

Here is how to select using class and title in plain JavaScript

 window.onload=function() { var sel = document.querySelector("select.r[title='State*']"); console.log(sel); sel.options[0]=null; } 

 <select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*"> <option>Please select State</option> <option>option 1</option> </select> <select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="NotState*"> <option>Please select Not State</option> <option>option 1</option> </select> 

Ditto in jQuery

 $(function() { var $options = $("select.r[title='State*'] option"); $options.eq(0).remove(); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> <select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*"> <option>Please select State</option> <option>option 1</option> </select> <select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="NotState*"> <option>Please select Not State</option> <option>option 1</option> </select> 

Answer 3

In your scenario if select box's id is changing dynamically then you can achieve this with it's class name like below

$(".r option[value='']").each(function() {
    $(this).remove();
});

If you want to delete it by using ID then you can do it like this..

$("#DROPDOWN_735 option[value='']").each(function() {
    $(this).remove();
});

Or

$("select option[value='']").each(function() {
    $(this).remove();
});

Answer 4

Try this

 $(document).ready(function() { $("select[title='State*'] option:first-child[value='']").remove(); }) 

  <script src="https://ajax.aspnetcdn.com/ajax/jQuery/jquery-3.1.1.min.js"></script> <select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*"> <option value="">Select One </option> <option value="Michigan"> Michigan</option> <option value="Alabama"> Alabama</option> <option value="Alaska"> Alaska</option> <option value="Arizona"> Arizona</option> <option value="Arkansas"> Arkansas</option> <option value="California"> California</option> <option value="Colorado"> Colorado</option> <option value="Connecticut"> Connecticut</option> <option value="Delaware"> Delaware</option> <option value="Florida"> Florida</option> <option value="Georgia"> Georgia</option> </select> <select name="DROPDOWN_735" class="r" id="DROPDOWN_735" title="State*"> <option value="">Select One </option> <option value="Michigan"> Michigan</option> <option value="Alabama"> Alabama</option> <option value="Alaska"> Alaska</option> <option value="Arizona"> Arizona</option> <option value="Arkansas"> Arkansas</option> <option value="California"> California</option> <option value="Colorado"> Colorado</option> <option value="Connecticut"> Connecticut</option> <option value="Delaware"> Delaware</option> <option value="Florida"> Florida</option> <option value="Georgia"> Georgia</option> </select>
