解决方案
给你的链接一个类(例如下载):
< a href =#class =downloaddata-bind =disable:noResults()....
您的下拉列表中的一个ID(例如dlDropDown):
< button class =btn dropdown-toggleid =dlDropDowndata-toggle =dropdowndata-bind =enable:!noResults()>
然后添加以下事件处理程序:
$(a.download)。click(function(){
$(#dlDropDown)。dropdown(toggle);
} );
I have a bootstrap dropdown menu below. It has a link in it hooked up to a knockout.js binding, that returns false because I dont want the # tag to be send to the browser url. However doing this doesnt close the dropdown menu when I click the link. Anyway around this?
HTML
<div class="btn-group">
<button class="btn dropdown-toggle" data-toggle="dropdown" data-bind="enable: !noResults()"><i class="icon-download-alt" ></i> Export <span class="icon-caret-down"></span></button>
<ul class="dropdown-menu">
@foreach(var exportUrl in Model.ExportUrls)
{
<li>
<a href="#" data-bind="disable: noResults(), download: { url: '@exportUrl.Value', data: data }"><img src="/Content/less/images/img/@(exportUrl.Key.ToString().ToLower()).png" alt="@exportUrl.Key.GetDisplayName()"/> @exportUrl.Key.GetDisplayName()</a>
</li>
}
</ul>
</div>
knockut.js binding
ko.bindingHandlers.download = {
init: function (element, valueAccessor) {
var value = ko.utils.unwrapObservable(valueAccessor()),
id = 'download-iframe-container',
iframe;
$(element).unbind('click').bind('click', function () {
iframe = document.getElementById(id);
if (!iframe) {
iframe = document.createElement("iframe");
iframe.id = id;
iframe.style.display = "none";
}
if (value.data) {
iframe.src = value.url + (value.url.indexOf('?') > 0 ? '&' : '?') + $.param(ko.mapping.toJS(value.data));
} else {
iframe.src = value.url;
}
document.body.appendChild(iframe);
return false;
});
}
};
解决方案
Give your links a class (e.g. download):
<a href="#" class="download" data-bind="disable: noResults()....
And your dropdown an id (e.g. dlDropDown):
<button class="btn dropdown-toggle" id="dlDropDown" data-toggle="dropdown" data-bind="enable: !noResults()">
And then add the following event handler:
$("a.download").click(function() {
$("#dlDropDown").dropdown("toggle");
});
