javascript - 如何从 Chosen JS 中删除搜索框？

Question

在 github 上，它说搜索框现在在所选选择框中是可选的。有谁知道怎么删除吗？

Answer 1

Chosen的当前版本提供了两种方法来控制搜索框的显示。两者都在初始化期间作为选项传入。要完全隐藏搜索框，请传入选项 "disable_search": true:

$("#mySelect").chosen({
  "disable_search": true
});

或者，如果您想在有一定数量的选项时显示搜索，请使用选项 "disable_search_threshold": numberOfOptions (其中 numberOfOptions 是最小数量显示搜索框之前所需的选项):

$("#mySelect").chosen({
  "disable_search_threshold": 4
});

jQuery(function($) {
  // Create a set of OPTION elements from some dummy data
  var words = ["lorem", "ipsum", "dolor", "sit", "amet,", "consectetur", "adipiscing", "elit", "duis", "ullamcorper", "diam", "sed", "lorem", "mattis", "tristique", "integer", "pharetra", "sed", "tortor"],
      options = $($.map(words, function(word) {
        return $(document.createElement('option')).text(word)[0];
      }));
  $('select').each(function() {
    // Add the dummy OPTIONs to the SELECT
    var select = $(this).append(options.clone());
    // Initialize Chosen, using the options from the
    // `data-chosen-options` attribute
    select.chosen(select.data('chosen-options'));
  });
});
