JavaScript: how to change form action attribute value based on selection?

Question

I'm trying to change the form action based on the selected value from a dropdown menu.

Basically, the HTML looks like this:

<form class="search-form" id="search-form" method="post" accept-charset="UTF-8" action="/search/user">
<select id="selectsearch" class="form-select" name="selectsearch">
<option value="people">Search people</option>
<option value="node">Search content</option>
</select>

<label>Enter your keywords: </label>
 <input type="text" class="form-text" value="" size="40" id="edit-keys" name="keys" maxlength="255" />

<input type="submit" class="form-submit" value="Search" id="edit-submit" name="search"/>
</form>

If "people" is selected, (which it is by default), the action should be "/search/user", and if content is selected, the action should be "/search/content"

I'm still searching around, but haven't been able to find out how to do this.

Solution 1

$("#selectsearch").change(function() {
  var action = $(this).val() == "people" ? "user" : "content";
  $("#search-form").attr("action", "/search/" + action);
});

Solution 2

If you only want to change form's action, I prefer changing action on-form-submit, rather than on-input-change. It fires only once.

$('#search-form').submit(function(){
  var formAction = $("#selectsearch").val() == "people" ? "user" : "content";
  $("#search-form").attr("action", "/search/" + formAction);
}); 

Solution 3

Simple and easy in javascipt

<script>

  document.getElementById("selectsearch").addEventListener("change", function(){

  var get_form =   document.getElementById("search-form") // get form 
  get_form.action =  '/search/' +  this.value; // assign value 

});

</script>

That is way better than what I was trying... Thank you

Worked perfect. Thanks. I updated this code to change the action on submit instead of on form change.

this.form.submit(); will have no sense since there are actually no forms an thus - nothing to submit

If you design for mobile devices it would be better to change action "on submit" for performance issues. Check my answer below.

Use prop instead of attr. Example = $("#search-form").prop ("action", "/search/" + action);

why would DOMElement setAttribute save any time over using jquery attr?
