how to control onTabClick

[KevinJonesChs]

I get a docs that use this :

$('.content-wrapper').IFrame({
onTabClick(item) {
return item;
},
onTabChanged(item) {
return item
},
onTabCreated(item) {
return item
},
autoIframeMode: true,
autoItemActive: true,
autoShowNewTab: true,
allowDuplicates: true,
loadingScreen: 750,
useNavbarItems: true
})

---

my code in this：

• 订单新增

关闭

关闭所有 关闭其它

欢迎使用

加载中......

---

and my javascript is :

$('.content-wrapper').IFrame({

onTabClick(ordercreate) {
console.log('123456789');
alert('onclictab!');
return ordercreate;
},
onTabChanged(item) {
return item
},
onTabCreated(item) {
return item
},
autoIframeMode: true,
autoItemActive: true,
autoShowNewTab: true,
allowDuplicates: true,
loadingScreen: 750,
useNavbarItems: true
})

I want know what is the 「item」 mean？ where can i set it ?

$('.content-wrapper').IFrame({
onTabClick(item) {
return item;
},
onTabChanged(item) {
return item
},
onTabCreated(item) {
return item
},
autoIframeMode: true,
autoItemActive: true,
autoShowNewTab: true,
allowDuplicates: true,
loadingScreen: 750,
useNavbarItems: true
})

my code is :

<ul class="nav nav-treeview">
    <li class="nav-item">
        <a href="/orders/1" class="nav-link" id="ordercreate" >
            <i class="far fa-circle nav-icon"></i>
            <p>订单新增</p>
        </a>
    </li>
</ul>


<div class="content-wrapper iframe-mode" data-widget="iframe" data-loading-screen="750">
        <div class="nav navbar navbar-expand navbar-white navbar-light border-bottom p-0">
            <div class="nav-item dropdown">
                <a class="nav-link bg-danger dropdown-toggle" data-toggle="dropdown" href="#" role="button"
                   aria-haspopup="true" aria-expanded="false">关闭</a>
                <div class="dropdown-menu mt-0">
                    <a class="dropdown-item" href="#" data-widget="iframe-close" data-type="all">关闭所有</a>
                    <a class="dropdown-item" href="#" data-widget="iframe-close" data-type="all-other">关闭其它</a>
                </div>
            </div>
            <a class="nav-link bg-light" href="#" data-widget="iframe-scrollleft"><i
                    class="fas fa-angle-double-left"></i></a>
            <ul class="navbar-nav overflow-hidden" role="tablist"></ul>
            <a class="nav-link bg-light" href="#" data-widget="iframe-scrollright"><i
                    class="fas fa-angle-double-right"></i></a>
            <a class="nav-link bg-light" href="#" data-widget="iframe-fullscreen"><i class="fas fa-expand"></i></a>
        </div>
        <div class="tab-content">
            <div class="tab-empty">
                <h2 class="display-4">欢迎使用</h2>
            </div>

                    <h2 class="display-4">加载中...... <i class="fa fa-sync fa-spin"></i></h2>
                </div>
            </div>
        </div>
    </div>

$('.content-wrapper').IFrame({
  onTabClick(ordercreate) {

      alert('onclictab!');
    return ordercreate;
