我需要在表单中显示错误。
如果在子节点中定义了错误,则可以将错误附加到输入名称表单,这是常见情况(1)。
但可能会发生错误在json对象(2)的根节点中定义 在这种情况下,它应该附加到formElement。
以下代码(3)适用于案例(1)但不适用于案例(2)。
如何修改它以使其在两种情况下都能正常工作? P.S。:我正在使用下划线和jquery。
(1)
var xhrObj_1 = JSON.parse('{ "children":{"points":{"errors":["This value should not be blank."]},"message":[],"recipient_id":{"errors":["This value should not be blank."]}}}');
(2)
var xhrObj_2 = JSON.parse('{ "errors":["This form should not be …."], "children":{"points":{"errors":["This value should not be blank."]},"message":[],"recipient_id":{"errors":["This value should not be blank."]}}}');
(3)
var parser = function (object) {
_.each(object, function (xhrObject, name) {
console.log(xhrObject)
if (xhrObject.errors) {
var inputElement = element.find('[name="' + name + '"]');
inputElement.closest('.control-group')
.addClass('error');
parserError(xhrObject.errors, inputElement);
} else {
parser(xhrObject); // it is ok for xhrObj_1
// it fails for xhrObj_2
}
});
};
// example with xhrObj_2 which does not work
parser({
"errors": ["errro1"],
"children": {
"points": {
"errors": ["This value should not be blank."]
},
"message": [],
"recipient_id": {
"errors": ["This value should not be blank."]
}
}
});

你应该在顶级开始递归:
var xhr = JSON.parse("…");
(function recurse(obj, name) {
if (obj.errors) {
var inputElement = element.find('[name="' + name + '"]');
inputElement.closest('.control-group').addClass('error');
parserError(obj.errors, inputElement);
}
if ("children" in obj)
for (var prop in obj.children)
recurse(obj.children[prop], prop);
})(xhr, "top");
