存入：

function GetInputData(id, cmd) {
var postdata = "{ \"action\":\"" + cmd + "\",";
$("#" + id + " input[type!='checkbox']").each(function () {
postdata += "\"" + $(this).attr("name") + "\":\"" + $(this).val() + "\",";
});
$("#" + id + " input[type='checkbox']").each(function () {
postdata += "\"" + $(this).attr("name") + "\":\"" + this.checked + "\",";
});
$("#" + id + " select").each(function () {
postdata += "\"" + $(this).attr("name") + "\":\"" + this.value + "\",";
});
$("#" + id + " textarea").each(function () {
postdata += "\"" + $(this).attr("name") + "\":\"" + this.value.replace(/\r|\n/g, "<br>") + "\",";
});
postdata = postdata.substr(0, postdata.length - 1);
postdata += "}";
return eval("(" + postdata + ")");
}

提交：var json = GetInputData("AthleteViolationInfoForm", "submit");

读取：

$("#ipt_actionresult").val(dataObj.ipt_actionresult.replace(/<br>/g, '\n'));//读取数据时把数据匹配正则替换正确的回车符号（符合的编码，用于正确显示）

alue.replace(/<br>/g, "");//替换换行为空
