How to re-direct to a page using button in drop down list(options_for_select)

How I can create a drop down list using select_tag "xyz", options_for_select or any way where on selecting any option from down list and hitting button will redirect me.

Any help??

<td> 
  <%= select_tag "options", options_for_select( 
                              [["Dashboard", 
                                "/homes/"+registrar.enrollment_application.id.to_s
                              ]] ) %>
</td> 
<input type="button" value="Select" onclick = "check_options()" > 

if above code is right then all i need to write a javascript??开发者_如何学Go please let me now

If you can use javascript or even jquery on the client side you could set the window.location based on the selected item in the drop down, after you click the button:

HTML: This is how you set up your select list and a button

<select id="options">
  <option value="http://stackoverflow.com">Stack Overflow</option>
  <option value="http://google.com/">Google</option>
</select>
<input type="button" id="optionsbutton" value="Go" />

JavaScript: This is how you wire up the button click to the window redirect

var onButtonClick = function() {
    window.location.replace($("#options").val()) //<--- This gets the selected value
                                                 //     and redirects the window
}

$(document).ready(function(){
    $("#optionsbutton").click(onButtonClick);  //<--- This hooks up the button click
                                               //     to do the onButtonClick function
});

See How to redirect to another webpage in JavaScript/jQuery? for more details.

Update Using Provided Code

You'd just have to make your check_options function find the selected value and set the window location:

var check_options = function() {
  window.location.replace($(" [ use selector for select element ] ").val());
});

You should add javascript like this

function check_options() { 
  window.location = document.getElementById("options").value
}
