mui mui-control-item获得选中的标签

function getActiveControl() {
var segmentedControl = document.getElementById("top-scroll");
var links = segmentedControl.getElementsByTagName('a');
for (var i = 0; i < links.length; i++) {
if (links[i].getAttribute('class').indexOf('mui-active') > 0) {
var id = links[i].getAttribute('href');
return id;
}
}
}
document.querySelectorAll(".mui-control-item").forEach(function(item){
item.addEventListener('tap', function () {
console.log(getActiveControl())
})
})

改进后：

<a class='mui-control-item' href="#item2mobile" val="16">女装</a>

document.querySelectorAll(".mui-control-item").forEach(function(item){
item.addEventListener('tap', function () {
var cat_id = item.getAttribute('val')
mui.ajax(__test_api_url+'/Tbk/optionalMaterialId', {
data:{
'token':__tbk_token,
'page':1,
'adzoneId':__adzone_id,
'catId':cat_id,
},
dataType: 'json',
type: 'post',
async: false,
headers: {'Content-Type': 'application/json'},
success: function (jsondata) {
console.log(jsondata);
},
});
})
})
