如何在自动完成中用空格替换下划线？

Question

I'm using jquery-ui to create a search dropdown, but I'd like to replace underscores with spaces in the dropdown results. I've tried.replace on the source but it doesn't seem to work.

Below is my autocomplete code. How do I use .replace(/_/g, " ") on it?

Thank you.

$(document).ready(function(){
    
    var alls = $.each([
    
    'Dr._Peppins',
    'Spain',
    'index',
    
    ],
    
    $( "#userInput" ).autocomplete({
    
    source: alls
    
    });
    
});

Answer 1

Try this:

 source: alls.replace("_", " ");

Answer 2

Consider the following.

 $(function() { var alls = [ 'Dr._Peppins', 'Spain', 'index', ]; function undScore2Space(word) { return word.replace("_", " "); } function filterArray(arr) { $.each(arr, function(i, e) { arr[i] = undScore2Space(e); }); return arr; } $("#userInput").autocomplete({ source: function(req, resp) { var results = $.ui.autocomplete.filter(alls, req.term); resp(filterArray(results)); } }); });

 <link rel="stylesheet" href="//code.jquery.com/ui/1.13.1/themes/base/jquery-ui.css"> <script src="https://code.jquery.com/jquery-3.6.0.js"></script> <script src="https://code.jquery.com/ui/1.13.1/jquery-ui.js"></script> <div class="ui-widget"> <label for="userInput">Input: </label> <input id="userInput"> </div>

In your example, you perform an Each. This is not properly formed and should generate an error.

In the case of an array, the callback is passed an array index and a corresponding array value each time. (The value can also be accessed through the this keyword, but Javascript will always wrap the this value as an Object even if it is a simple string or number value.) The method returns its first argument, the object that was iterated.

So you do not want to initialize Autocomplete on each item in the array. You can modify each part if you choose, yet if you expect the source to contain these characters, it would be best to filter them out after the lookup.

You can make use of a function for source and perform events this way.

You can also do the following:

$(document).ready(function(){
    var alls = [];
    $.each([
      'Dr._Peppins',
      'Spain',
      'index'
    ], function(index, elem){
      alls.push(elem.replace("_", " "));
    });
    $("#userInput").autocomplete({
      source: alls
    });
});
