尝试在DOM中的特定可折叠元素上执行open()
方法,并调用以下函数:
vm.openCollapsible = function( projectName )
{
// This element is the span that contains the project name
var element = getElementsByText(projectName);
// We want to reach out its parent which has collapsible as a class and
// it's 3 elements upwards.
//console.log(element[0].parentElement.parentElement.parentElement);
var collapsible_element = element[0].parentElement.parentElement.parentElement;
var instance = M.Collapsible.getInstance(collapsible_element);
console.log(instance);
instance.open(0);
}
我确定选择了正确的元素,因为console.log(instance)
向我返回了一个有效的对象。
s {el: ul.collapsible.collapsible-accordion, $el: g(1), options: {…}, $headers: g(1), _handleCollapsibleClickBound: ƒ, …}
$el: g [ul.collapsible.collapsible-accordion]
$headers: g [div.collapsible-header.waves-effect.project-toolbar-box]
el: ul.collapsible.collapsible-accordion
options: {accordion: true, onOpenStart: undefined, onOpenEnd: undefined, onCloseStart: undefined, onCloseEnd: undefined, …}
_handleCollapsibleClickBound: ƒ ()
_handleCollapsibleKeydownBound: ƒ ()
__proto__: s
有什么想法吗?
答案 0 :(得分:0)
使用以下命令打开所需的可折叠元素: $('。collapsible')。collapsible('open',0);
0表示索引,您应该相应地对其进行更改。
