>我使用以下代码创建自定义按钮:
const clusterShowButton = new ymaps.control.Button({ data: {
content: SVG_CLUSTER_SHOW,
title: 'Отключить кластеризацию',
selectOnClick: true,
size: 'small'
}
});
之后,我正在尝试分配一些CSS类:
clusterShowButton._layout._buttonElement.className += 'my-button';
这适用于所有除Internet Explorer 11以外的浏览器(甚至在Microsoft Edge中)。经过进一步调查,我意识到在IE11中clusterShowButton._layout
为空。
问题:
- 如何分配自定义类?(我知道更改以下划线命名的私有属性不太正确)
- 是YandexMaps的错误吗?
您可以参考代码为自定义按钮添加按钮布局,然后添加类:
ymaps.ready(init);
function init() {
var myMap = new ymaps.Map('map', {
center: [55.650625, 37.62708],
zoom: 10,
controls: []
}),
/**
* The button layout should display the 'data.content' field
* and change depending on whether the button was clicked or not.
* The current size (small, medium, large) is calculated from the value of the 'maxWidth' option
* @see https://api.yandex.ru/maps/doc/jsapi/2.1/ref/reference/control.Button.xml#param-parameters
*/
ButtonLayout = ymaps.templateLayoutFactory.createClass([
'<div title="{{ data.title }}" class="my-button ',
'{% if state.size == "small" %}my-button_small{% endif %}',
'{% if state.size == "medium" %}my-button_medium{% endif %}',
'{% if state.size == "large" %}my-button_large{% endif %}',
'{% if state.selected %} my-button-selected{% endif %}">',
'<img class="my-button__img" src="{{ data.image }}" alt="{{ data.title }}">',
'<span class="my-button__text">{{ data.content }}</span>',
'</div>'
].join('')),
button = new ymaps.control.Button({
data: {
content: "Click-click-click",
image: 'images/pen.png',
title: "Click-click-click"
},
options: {
layout: ButtonLayout,
maxWidth: [170, 190, 220]
}
});
myMap.controls.add(button, {
right: 5,
top: 5
});
}
