在微信公众号中，xmlContent为html，IOS系统可以将xmlContent传到后台，android不行，如何书写才可以让android也行？
代码如下：
function submitPjVisitRec(){
var openId="<%=user.getOpenId()%>";
var patientId= document.getElementById("patientId").value;
var visitFlow= document.getElementById("visitFlow").value;
var projectFlow= document.getElementById("projectFlow").value;
var tplID= document.getElementById("tplID").value;
var edcRecordFlow="<%=edcRecordFlow%>";
var xmlContent=document.all.xmlContentDiv.innerHTML;
var xmlContent2=encodeURIComponent(encodeURIComponent(xmlContent));
var url="web?operation=save_health_assessment&menu_type=user&patientId="+patientId+"&visit_flow="+visitFlow+"pj_flow="+projectFlow+"&open_id="+openId+"&tplID="+tplID+"&xmlContent="+xmlContent2;
ht.request({
url : url,
form:auditContentForm,
callback : function(response) {
if (response == "ok") {
alert("提交成功！");
document.getElementById("saveBtn").disabled=true;
window.location.href = "web?operation=health_assessment&menu_type=user&patientId="+patientId+"&visit_flow="+visitFlow+"pj_flow="+projectFlow+"&edcRecordFlow="+edcRecordFlow+"&tplID="+tplID;
} else {
alert("提交失败！");
}
}
});
}
