我在html中有一个按钮,可以这样说:
<button type="button">Button</button>
我希望能够通过烧瓶禁用此按钮(例如,在按下按钮之后)。我想知道的是如何将 disabled 属性添加到按钮上。换句话说,将其变成:
<button type="button" disabled>Button</button>

在路线终点致电var vehicleList = [
{vanNumber: "7654628", vanDescription: "VW Campervan", value: {make: "VW", amount: 11660}},
{vanNumber: "9873093", vanDescription: "Renault Campervan", value: {make: "Renault", amount: 3429}},
{vanNumber: "1739566", vanDescription: "Nissan Campervan", value: {make: "Nissan", amount: 5600}},
{vanNumber: "3949219", vanDescription: "VW", value: {make: "VW", amount: 1960}}
];
function collectAndGroupVehicleItemByBrand(collector, vehicleItem) {
var
list = collector.list,
index = collector.index,
make = vehicleItem.value.make,
group;
if (make in index) {
group = index[make];
} else {
group = index[make] = { make: make, count: 0, list: [] };
list.push(group);
}
group.count = group.list.push(vehicleItem);
return collector;
}
var dictionary = vehicleList.reduce(collectAndGroupVehicleItemByBrand, {
list : [],
index : {}
});
console.log('groupedVehicleList : ', dictionary.list);
console.log('groupedVehicleIndex : ', dictionary.index);
时,请传递一个布尔值:
.as-console-wrapper { max-height: 100%!important; top: 0; }
您可以在路线中设置return render_template('template.html', variables=values)
的值。然后在您的jinja2模板中,只需放入一个分支:
return render_template('template.html', var1=val1, var2=val2,..., button=button)
如果需要在页面呈现后动态禁用按钮,则@ ltd9938是正确的,则需要使用javascript。
我现在读的意思是在推入之后,是的,是的,您需要使用javascript。
