Append text field value to URL using jQuery

Question

I have a list of URLs:

localhost/action/add/234
localhost/action/add/244
localhost/action/add/334
localhost/action/add/254

In front of these values there is a text box, and when a value is typed into the box I want to append it to the end of the URL.

localhost/action/add/234/test text1
localhost/action/add/244/test text2
localhost/action/add/334/test text3
localhost/action/add/254/test text4

Can someone explain me how can I do it? I found out that its possible to do it using .val() but I'm unsure how to use it.

Answer 1

If you want it to update immediately:

<script>
  $(function(){
    var a = $('#url').text();
    $('#textbox').keyup(function(){
      var b = $('#textbox').val();
      $('#url').text(a + '/test ' + b);
      $('#url').attr('href', a + '/test ' + b);
    });
  });
</script>

<input id='textbox' type='text'></input>
<a href="localhost/action/add/234" id='url'>localhost/action/add/234</a>

The key things here are

• use the .keyup() event to run the function whenever a keyboard key is released
• modify the .text() of the url element on keyup
• modify the 'href' attribute of the url element so that the link matches the text

Normally .val() is used to set/get the value of input elements, like the text box ^, or a dropdown

Answer 2

Assuming, you want to append the text that you typed in the textfield to the href (URL). I think we can make it more simple.

Here is the working solution.

 $(document).ready(function(){ $('#search').on('click', function(e) { var search_url = e.originalEvent.currentTarget.href; //or else you can grab the URL anywhere from your DOM; e.originalEvent.currentTarget.href = search_url + $('#search_term').val(); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <input type="text" id="search_term" placeholder="Search..StackOverflow" /> <a href="https://stackoverflow.com/search?q=" id="search">Search </a>

 $(function(){ var currVal = $('.url').text(); $('input[type="text"]').keydown(function() { $('.url').text(currVal.trim()+$(this).val().trim()); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <span class="url"> localhost/action/add/234 </span> <input type="text" id="search_term" placeholder="blabla" />
