jQuery的ajax调用很方便,传参的时候喜欢用Json的数据格式。比如:
function AddComment(content) {
var threadId = $(\"#span_thread_id\").html();
var groupId = $(\"#span_group_id\").html();
var groupType = $(\"#span_group_type\").html();
var title = $(\"#thread_title\").html();
var content = content.replace(/\\x22/g,\'\"\');
$.ajax({
url: \'/WebService/GroupService.asmx/AddThreadComment\',
data: \'{threadId:\' + threadId + \',groupId:\' + groupId + \',groupType:\' + groupType + \',title:\"\' + title + \'\",content:\"\' + content + \'\"}\', type: \'post\',
dataType: \'json\',
contentType: \'application/json;charset=utf-8\',
cache: false,
success: function(data) {
//根据返回值data.d判断是不是成功
},
error: function(xhr) {
//中间发生异常,查看xhr.responseText
}
});
}
这中间最麻烦,最容易出错的也是拼接Json字符串,字符型参数的值要添加引号,而且对于用户输入的文本字段要对\',/等进行特殊处理
意外的机会,上司给我推荐了一种新的方法,看下面代码:
function AddComment(content) {
var comment = {};
comment.threadId = $(\"#span_thread_id\").html();
comment.groupId = $(\"#span_group_id\").html();
comment.groupType = $(\"#span_group_type\").html();
comment.title = $(\"#thread_title\").html();
comment.content = content;
$.ajax({
url: \'/WebService/GroupService.asmx/AddThreadComment\',
data: $.toJSON(comment),
type: \'post\',
dataType: \'json\',
contentType: \'application/json;charset=utf-8\',
cache: false,
success: function(data) {
//根据返回值data.d处理
},
error: function(xhr) {
//中间发生异常,具体查看xhr.responseText
}
});
}
直接用$.toJSON(对象)即可;
