bootstrap tree-view加载时选中某个节点

[mozishu]

修改页面加载时，要触发tree-view的某个节点的选中事件，知道这个节点的id.

[{"tags":0,"text":"根目录","nodes":[{"tags":1,"id":1,"text":"听障","sort":1,"nodes":[{"tags":2,"id":2,"text":"构音部位","sort":1,"nodes":[{"tags":3,"id":3,"text":"唇音","sort":1,"nodes":[{"tags":4,"id":4,"text":"b","sort":1,"nodes":[{"tags":5,"id":5,"text":"开口","sort":1,"nodes":[{"tags":6,"id":6,"text":"理解","sort":1,"nodes":[{"tags":7,"id":7,"text":"速检","sort":1,"pid":6,"code":"1","type":"检测/训练","isEnabled":0}],"pid":5,"code":"1","type":"理解/产出","isEnabled":0}],"pid":4,"code":"001","type":"单元","isEnabled":0}],"pid":3,"code":"001","type":"组","isEnabled":0}],"pid":2,"code":"001","type":"子域","isEnabled":0}],"pid":1,"code":"01","type":"域","isEnabled":0},{"tags":2,"id":17,"text":"testaa","sort":12,"description":"","pid":1,"code":"12","type":"域","isEnabled":0}],"pid":0,"code":"01","type":"类","isEnabled":0},{"tags":1,"id":8,"text":"SLI","sort":2,"nodes":[{"tags":2,"id":10,"text":"test2","sort":2,"description":"123","pid":8,"code":"01","type":"域","isEnabled":0}],"pid":0,"code":"04","type":"类","isEnabled":0}],"pid":0,"isEnabled":0}]

这个是，树形菜单的json字符串

这里你首先要获取到一个想要选中节点的Id，我这里是MenuIdList,另外一个参数就是treeview需要的json字符串，实际上是一个数组。 我这里定义一个方法，递归的方式，将state属性中的checked设置为true。本人亲测有效，如果还不懂可以问我 function traverse(arr,menuIdList) { for (var a in arr) { for(var i in menuIdList){ if(arr[a].id == menuIdList[i]){ arr[a]['state'] = {checked:true}; menuIdList.splice(i,1); break; } } if (typeof(arr[a].nodes) == "object") { traverse(arr[a].nodes,menuIdList); //递归遍历 } } }
