我在流星上工作,并试图在选中复选框时显示代码块。我是JS和jquery的新手,但是我研究了编写JS的不同方法。这是我想出的:
<div class="recipient">
<div class="toRecipient-container">
<label class="toRecipient">TO:</label>
<input class="toRecipient" type="text" size="45">
</div>
<br>
<div id="checkbox-container" class="checkbox-container">
<label for="newClient">New Client
<input id="newClient" class="newInfo" type="checkbox" onclick="toggle()"></label>
<label for="newBilling" style="padding-left: 20px;">New Billing
<input id="newBilling" class="newInfo" type="checkbox"></label>
</div>
</div>
<div id="billingDetails-container" class="billingDetails-container">
<div class="billingDetails">
<label>Billing Contact:</label>
<input class="billingContact" type="text" size="45">
<label>Billing Phone:</label>
<input class="billingPhone" type="text" size="45">
<div>
<label>Billing Address:</label>
<input class="billingAddress" type="text" placeholder="Street Address" size="45">
<input class="billingAddress" type="text" placeholder="City" size="45">
<input class="billingAddress" type="text" placeholder="State" size="45">
<input class="billingAddress" type="text" placeholder="Zip Code" size="45">
</div>
<label>Billing Email:</label>
<input class="billingEmail" type="text" size="45">
</div>
</div>
还有我的JS:
Template.InvoicePage.onCreated(function () {
this.state = new ReactiveVar();
});
Template.InvoicePage.helpers({
toggle: ()=>{
var checkBox = document.getElementById("newClient");
var displayBlock = document.getElementById("billingDetails-container");
if (checkBox.checked == true) {
displayBlock.style.display = "block";
} else {
displayBlock.style.display = "none";
}
},
});
Template.InvoicePage.events({
'change #newClient'(event, instance) {
instance.state.set('newClient', event.target.checked)
},
});
当我选中此框时,我收到一个错误,指出“ toggle”未定义。这应该是模板事件,而不是辅助事件吗?我想念什么?
答案 0 :(得分:0)
我从没做过流星。网站上列出了许多不同的框架。我不确定您使用哪一个(如果有)。您不可能同时使用angular,react和vuejs。
除非我错了,并且整个情况有一个特殊的原因
Template.InvoicePage.helpers({...});
简单地做
function toggle() {
var checkBox = document.getElementById("newClient");
var displayBlock = document.getElementById("billingDetails-container");
if (checkBox.checked == true) {
displayBlock.style.display = "block";
} else {
displayBlock.style.display = "none";
}
}
它与框架无关。只是普通的javascript和html。
