Question

我有一个带有某些值的输入，我尝试获取该值。当我单击“有效”按钮时，显示为“未定义”。这是我的jsfiddle：http://jsfiddle.net/pv2we0x3/1/

$(function() {
  $('.suggest-tag').magicSuggest({
    data: [{
      "Id": 1,
      "Name": "hello"
    }, {
      "Id": 2,
      "Name": "world"
    }, {
      "Id": 3,
      "Name": "no"
    }],
    valueField: 'Id',
    displayField: 'Name',
  });

  $('.btn').click(function() {
    alert($('.suggest-tag').serialize());
  })
});

根据documentation for MagicSuggest，您需要在创建的库实例上调用getValue()，以获取选定的标签值：

$(function() {
  var ms = $('.suggest-tag').magicSuggest({
    data: [{
      "Id": 1,
      "Name": "hello"
    }, {
      "Id": 2,
      "Name": "world"
    }, {
      "Id": 3,
      "Name": "no"
    }],
    valueField: 'Id',
    displayField: 'Name',
  });

  $('.btn').click(function() {
    console.log(ms.getValue());
  })
});
