問(wèn)題描述

問(wèn)題出在 data-bind='click: selecttag這句代碼
瀏覽器報(bào)錯(cuò) selecttag is not define
但以前一直是這么寫(xiě)的呀..沒(méi)出過(guò)問(wèn)題..怎么今天就報(bào)錯(cuò)了呢....

<ul class="file-tags-ul">
    <!-- ko foreach: filetags -->
    <li data-bind="attr: {style:leftlinear},css:{isselect}">
        <a href="javascript:void(0);" data-bind='click: selecttag,attr: {title: descsum },text: desc'></a>
        <div data-bind="attr: {style:linear}"></div>
    </li>
    <!-- /ko -->
</ul>

js

var FileViewModel = function() {
        var self = this;
    
    self.selecttag = function(){
        console.log(this)
    };
}

解決方法

去掉前面的 self. 就好了.

js

var FileViewModel = function() {
        var self = this;
    
    selecttag = function(){
        console.log(this)
    };
}
