最好的方法是用knockout.js使一个纽芬兰州陷入双重点击,我有一些用户迅速点击,提出多重亚克斯要求。 我假定,js可以以几种方式处理此事,希望那里看到一些替代办法。

使用ema(lock锁)。 基本上,你估计有多少人点击了某一要素的登记,如果是超过1人,你就会退回不实之处,也不允许进行以下点击。 可以使用排时功能清除锁锁,以便它们在5秒后再次点击。 http://knockoutjs.com/documentation/click- binding.html
如下文所示:
<div>
You ve clicked <span data-bind="text: numberOfClicks"></span> times
<button data-bind="click: incrementClickCounter">Click me</button>
</div>
<script type="text/javascript">
var viewModel = {
numberOfClicks : ko.observable(0),
incrementClickCounter : function() {
var previousCount = this.numberOfClicks();
this.numberOfClicks(previousCount + 1);
}
};
</script>
By changing the logic inside the nested function to
if( this.numberOfClicks() > 1 ){
//TODO: Handle multiple clicks or simply return false
// and perhaps implement a timeout which clears the lockout
}
我也遇到了类似的问题,在纽特州点击Ajax提交数据的形式令人迷惑。 我们有4个县,每个步骤都有选择性的可见度。 我们创建了一个可观测到的风气ButtonLock
,如果是真的,则从呈文功能中恢复。 然后,我们也将数据输入到<条码>可分条码>,每个纽吨<条码>。
观点:
var viewModel = function(...) {
self.ButtonLock = ko.observable(false);
self.AdvanceStep = function (action) {
self.ButtonLock(true);
// Do stuff
// Ajax call
}
self.AjaxCallback = function(data) {
// Handle response, update UI
self.ButtonLock(false);
}
Button:
<input type="button" id="FormContinue" name="FormContinue" class="ActionButton ContinueButton"
data-bind="
if: CurrentStep().actions.continueAction,
disable: ButtonLock,
value: CurrentStep().actions.continueAction.buttonText,
click: function() {
AdvanceStep(CurrentStep().actions.continueAction);
}"/>
如果你只需要防止多次点击,我更喜欢 b。 但是,如果你想要这一特征,反制方法让你发现双点,单独处理。
如果有的话,人们仍在寻求这样做的办法。 我发现,你可以使用ean。
self.disableSubmitButton= ko.observable(false);
self.SubmitPayment = function () {
self.disableSubmitButton(true);
//your other actions here
}
接着,你认为
data-bind="click:SubmitPayment, disable:disableSubmitButton"
我这样做的习俗是具有约束力的:
<button data-bind="throttleClick: function() { console.log(new Date()); }>
I wont double click quicker than 800ms
</button>
ko.bindingHandlers.throttleClick = {
init: function(element, valueAccessor) {
var preventClick = false;
var handler = ko.unwrap(valueAccessor());
$(element).click(function() {
if(preventClick)
return;
preventClick = true;
handler.call();
setTimeout(function() { preventClick = false; }, 800);
})
}
}
