Javascript 无法从<;调用视图模型中的函数;内容>;要素
当我单击按钮Javascript 无法从<;调用视图模型中的函数;内容>;要素,javascript,html,aurelia,aurelia-dialog,aurelia-templating,Javascript,Html,Aurelia,Aurelia Dialog,Aurelia Templating,当我单击按钮#btn1或#btn2保存时,控制台显示: Uncaught Error: save is not a function getFunction @ aurelia-binding.js:1971 evaluate @ aurelia-binding.js:1565 callSource @ aurelia-binding.js:4989 (anonymous function) @ aurelia-binding.js:5013 handle
#btn1
或#btn2
保存时,控制台显示:
Uncaught Error: save is not a function
getFunction @ aurelia-binding.js:1971
evaluate @ aurelia-binding.js:1565
callSource @ aurelia-binding.js:4989
(anonymous function) @ aurelia-binding.js:5013
handleDelegatedEvent @ aurelia-binding.js:3211
但是outter按钮可以正常工作。我还在#btn2
中尝试$parent.save()。有什么想法吗
app.html
<create-location contact.two-way="contact" working-time.two-way="workingTime">
<require from="dist/component/working-time"></require>
<working-time title="Working Time" view-model.ref="workingTime"></working-time>
<require from="dist/component/contact"></require>
<contact title="Contact" phone="123" email="user@example.com" fax="123456" view-model.ref="contact"></contact>
<button id="btn1" type="button" click.delegate="save()">Save (=>error<=)</button>
<button id="btn2" type="button" click.delegate="$parent.save()">Save (=>error also<=)</button>
</create-location>
<template>
<button id="btn3" type="button" click.delegate="save()">Save (=>it works<=)</button>
<content></content>
</template>
更新
我试过法比奥的建议,然后
另一个问题:看,他们在
元素中调用了视图模型的testDelegate
函数,类似于我的例子。他们不使用视图model.ref
。我看了一下源代码,但没有发现他们在哪里处理这个调用。也许我错过了一些要点,或者这里有一些惯例。有人知道他们是如何做到这一点的吗?您可以使用视图模型.ref将创建位置的视图模型放在属性中,然后使用该属性调用保存()
。像这样:
<create-location view-model.ref="createLocationVM" contact.two-way="contact" working-time.two-way="workingTime">
<require from="dist/component/working-time"></require>
<working-time title="Working Time" view-model.ref="workingTime"></working-time>
<require from="dist/component/contact"></require>
<contact title="Contact" phone="123" email="user@example.com" fax="123456" view-model.ref="contact"></contact>
<button id="btn1" type="button" click.delegate="createLocationVM.save()">Save (=>error<=)</button>
</create-location>
保存(=>错误因为创建位置页面是服务器上的预渲染页面,我希望aurelia控制浏览器上的整个页面(使用绑定、自定义组件等),所以我创建创建位置
组件并使用aurelia增强功能()。我想知道这是否是一种正确的方法。你做过类似的事情吗?顺便说一句,看看。他们有一个testDelegate
函数,但我不知道怎么做。他们根本不使用view model.ref
。
<create-location view-model.ref="createLocationVM" contact.two-way="contact" working-time.two-way="workingTime">
<require from="dist/component/working-time"></require>
<working-time title="Working Time" view-model.ref="workingTime"></working-time>
<require from="dist/component/contact"></require>
<contact title="Contact" phone="123" email="user@example.com" fax="123456" view-model.ref="contact"></contact>
<button id="btn1" type="button" click.delegate="createLocationVM.save()">Save (=>error<=)</button>
</create-location>
