minChars in autocomplete() not working

I am doing demo for autocomplete using jquery plugin. I have to set the minimum character lengt开发者_StackOverflow社区h to 3. I have changed minChars : 3 in its default options values.

$.Autocompleter.defaults = {
    inputClass: "ac_input",
    resultsClass: "ac_results",
    loadingClass: "ac_loading",
    minChars: 3,
    delay: 400,
    matchCase: false,
    matchSubset: true,
    matchContains: false,
    cacheLength: 10,
    max: 100,

Also I tried it by changing adding the minChar parameter on autocomplete() call like:

   $("#inputSchool").autocomplete(data, "option", "minChars", 3);
   and also like :
   $("#inputSchool").autocomplete(data, "{minChar : 3}");

But yet is is not working. Please tell me the solution.

And How to Edit the format of autocomplete list? i.e. I have to add multiple values html like :

<ul>
   <li>value1, value2 
       <br /> 
       value3
   </li>
</ul>

Please Help me?

Are you searching something like :

$( ".selector" ).autocomplete({ minLength: 3 }); // Not minChars
//or
$("#inputSchool").autocomplete("option", "minLength", 3);

Try:

   $("#inputSchool").autocomplete(data, {minChars : 3});
