Question

我有一个问题，其中以下代码在错误的元素上触发，下面的代码在名为tag的jQuery小部件的_create函数内，但是当我单击下面gif中的x按钮时，它将删除“ goo”标签而不是“ yoo”，但是我单击了“ yoo”

if(this.options.removable)
{

        this.removeButton = $("<span class='close glossy'>x</span>").appendTo(this.element);
        console.log(this.removeButton.parent().text());

        this.removeButton.click(function(e){
            alert(self.element.text());
            self._destroy();

            e.preventDefault();
        });
}

这是最终的html代码供参考

谢谢。

这是小部件的完整JS代码

$.widget( "search.tagify", {

options: {
    followerCount: 30,
    description: 

    `a Javascript library, consider also adding the Javascript tag. jQuery is a
     popular cross-browser JavaScript library that facilitates
      Document Object Model (DOM) traversal, 
     event handling…,`,

    name: "tag name goes here",
    removable: false
},

_destroy: function()
{
    //Tips.remove(this.element);
    this.element.remove();
},

_create: function() {
    self = this;

    this.element
        .addClass( "tag" )
        .text( this.options.name )
        .protipSet({
            title: this.options.description,
            position: "bottom",
            size: "small",
            skin: "square",
            classes: "tag-tooltip",
        })

    if(this.options.removable)
    {

        this.removeButton = $("<span class='close glossy'>x</span>").appendTo(this.element);
        console.log(this.removeButton.parent().text());

        this.removeButton.click(function(e){
            alert(self.element.text());
            self._destroy();

            e.preventDefault();
        });
    }

},

});

请检查以下代码。

if(this.options.removable)
{

    this.removeButton = $("<span class='close glossy'>x</span>").appendTo(this.element);
    console.log(this.removeButton.parent().text());

    this.removeButton.click(function(e){
        alert(self.element.text());
        //here is the change you can access the targeted element like this as well
        $(e.target).parent('.tag').remove();

        e.preventDefault();
    });
}

我对代码进行了更改，请检查，我显示了选择目标的另一种机制
