我在下面的代码段中使用jquery和select2创建了标签输入。

$(document).ready(function() {
  
  $("#tag-input .js-example-basic-multiple").select2({
    placeholder: "Add tag"
  }).on('change', function(e) {
    if($(this).val() && $(this).val().length) {
      $(this).next('.select2-container').find('li.select2-search--inline input.select2-search__field').attr('placeholder', 'Add tag');
    }
  });
});

如您所见，输入字段看起来就像插入标签一样。有没有办法将插入的标签放在输入的右边？这样我的输入将保留在容器的左侧。

有人可以帮我吗？任何帮助表示赞赏！ ：）

答案 0 :(得分：1)

从我的previous post到change函数中添加代码以分离搜索<li> 并将其添加到<ul class="select2-selection__rendered">之前，这是更改将输入标签保留在左侧，并继续将所选选项向右移动。

$("#tag-input .js-example-basic-multiple").select2({
  placeholder: "Add tag"
}).on('change', function(e) {
    if($(this).val() && $(this).val().length) {
       var searchItem = $(this).next('.select2-container').find('li.select2-search--inline').detach();

       var renderList = $(this).next('.select2-container').find('ul.select2-selection__rendered').prepend(searchItem);
       searchItem.find('input.select2-search__field').attr('placeholder', 'Add tag');

    }
});

代码段： 

$(document).ready(function() {
  
  $("#tag-input .js-example-basic-multiple").select2({
    placeholder: "Add tag"
  }).on('change', function(e) {
    if($(this).val() && $(this).val().length) {
    	var searchItem = $(this).next('.select2-container').find('li.select2-search--inline').detach();
      
      var renderList = $(this).next('.select2-container').find('ul.select2-selection__rendered').prepend(searchItem);
      searchItem.find('input.select2-search__field').attr('placeholder', 'Add tag');
      
    }
  });
});
