选择 2 ->添加数据而不替换内容 [英] SELECT2 -> Add data without replacing content

问题描述

我看过其他一些主题，但没有那么具体.这并不是我认为很难的事情，但我不确定如何去做.

I've had a look at some other threads but nothing quite as specific. It's not really something that I would assume is hard but I'm not sure how about to do it.

目前我将 Select2 用于标记系统，在它旁边我有建议的标签，用户可以点击这些标签并将其添加到框中.

Currently I'm using Select2 for a tagging system and next to it I have suggested tags which users would be able to click on and it will add to the box.

相反，每个标签都在替换内容并添加自身.

Instead, each tag is replacing the content and adding itself.

我需要将添加内容附加到框中，而不替换其中已有的内容.

I need the adding to be appended into the box without replacing what's already in there.

这是我的代码:

$(document).on('click', ".tag1", function () {
      var value = $(".tag1").html();
      console.log(value);
      $("#selectPretty").val([value]).trigger("change");
});
$(document).on('click', ".tag2", function () {
      var value = $(".tag2").html();
      console.log(value);
      $("#selectPretty").val([value]).trigger("change");
});

数据是通过 AJAX 拉取的，每个建议标签都有一个跨度.

The data is being pulled through via AJAX with a span around each suggested tag.

希望我足够清楚.

总结:我希望能够点击每个标签"并添加它，而不是替换框中已有的内容.

Summary: I want to be able to click on each 'tag' and for it to be added, instead it replaces what was already in the box.

谢谢

推荐答案

您应该能够通过简单的方式做到这一点:

You should be able to do that with simple:

var test = $('#test');

$(test).select2({
    data:[
        {id:0,text:"enhancement"},
        {id:1,text:"bug"},
        {id:2,text:"duplicate"},
        {id:3,text:"invalid"},
        {id:4,text:"wontfix"}
    ],
    multiple: true,
    width: "300px"
});
var data = $(test).select2('data');
data.push({id:5,text:"fixed"});
$(test).select2("data", data, true); // true means that select2 should be refreshed
