Answer 1

有children

Answer 2

一个大坑  不知道easyui设计人员干什么吃的

Answer 3

把后台传递的json数据里的字段name改写成text试试

Answer 4

combotree中的tree继承自tree，并没有实现combobox的valueField和textField属性，需要自己写loadFilter:
参考：
//作者孙宇
//自定义loadFilter的实现
$.fn.tree.defaults.loadFilter = function (data, parent) {
var opt = $(this).data().tree.options;
var idField,
textField,
parentField;
if (opt.parentField) {
idField = opt.idField || 'id';
textField = opt.textField || 'text';
parentField = opt.parentField; var i,
l,
treeData = [],
tmpMap = []; for (i = 0, l = data.length; i < l; i++) {
tmpMap[data[i][idField]] = data[i];
} for (i = 0, l = data.length; i < l; i++) {
    if (tmpMap[data[i][parentField]] && data[i][idField] != data[i][parentField]) {
        if (!tmpMap[data[i][parentField]]['children'])
            tmpMap[data[i][parentField]]['children'] = [];
data[i]['text'] = data[i][textField];
tmpMap[data[i][parentField]]['children'].push(data[i]);
} else {
data[i]['text'] = data[i][textField];
treeData.push(data[i]);
}
}
return treeData;
}
return data;
};

Answer 5

人家json里面需要的明明是 id 和 text 作为key，所以嘛就undefined喽

Answer 6

确实是这样！不过你这个代码是处理多级数据扁平json的，如果要同时处理自定义idField和valueField，可以这样：//自定义EasyUI.tree loadFilter实现
$.fn.tree.defaults.loadFilter = function (data, parent) {
var opt = $(this).data().tree.options;
var idField, textField, parentField;
if(opt.idField || opt.valueField || opt.textField || opt.parentField){
idField = opt.idField || opt.valueField || 'id'; //idField和valueField可以混用
textField = opt.textField || 'text';
parentField = opt.parentField; var i, l, treeData = [], tmpMap = [];
for (i = 0, l = data.length; i < l; i++) {
tmpMap[data[i][idField]] = data[i];
} for (i = 0, l = data.length; i < l; i++) {
    if (parentField && tmpMap[data[i][parentField]] && data[i][idField] != data[i][parentField]) {
        if (!tmpMap[data[i][parentField]]['children'])
            tmpMap[data[i][parentField]]['children'] = [];
data[i]['id'] = data[i][idField];
data[i]['text'] = data[i][textField];
tmpMap[data[i][parentField]]['children'].push(data[i]);
} else { //处理扁平化数据（如果可预知数据是单层的，建议直接使用combobox而不是combotree）
data[i]['id'] = data[i][idField];
data[i]['text'] = data[i][textField];
treeData.push(data[i]);
}
}
return treeData;
}
return data;
};
$.fn.combotree.defaults.loadFilter = $.fn.tree.defaults.loadFilter; //这里要加上，否则combotree不会生效
