我是jquery和数据表中的新手, 我在使用功能为来自另一页面的元素输入设置值时遇到问题。
这是我的第一页代码
{
data: "action_user",
targets: "action_user",
mRender: function (data_app, type_app, row_app) {
if (row_app["id_user"] !== null) {
var va_id_user = row_app["id_user"];
var va_user_name = row_app["user_name"];
var va_gender = row_app["gender"];
var va_address = row_app["address"];
var va_imei = row_app["imei"];
var va_phone = row_app["phone"];
var va_role_name = row_app["role_name"];
var va_email = row_app["email"]; //,supplier_name,supplier_code,address,contact_name,contact_num,status_supp
var va_status_user = row_app["status_user"]; // <a href='#'id='updateDataUser' onclick='javascript:myFunc(" + supplier_id + ")'><i class='fa fa-edit'title='Edit'></i></a>\n\
var data_users = {
id_user: va_id_user,
user_name: va_user_name,
gender: va_gender,
imei: va_imei,
phone:va_phone,
address:va_address,
role_name: va_role_name,
email: va_email,
status_user: va_status_user
};
return"<a id='updateDataUser' href='#' onclick='javascript:editUserFunc(" + JSON.stringify(data_users) + ")'><i class='fa fa-edit activeRecord' rel='13' title='Edit'></i></a>";
// return "<a href='" + data_pict_1 + " 'target='_blank' class='btn btn-info'>" + "<font color='#f2f2f2' size='2em'>" + "Display" + "</font>" + "</a>";
}
}
}
这是我的html代码
<div id="div_add_pic" class="panel panel-default">
<form id="form_add_pic" name="form_add_pic" method="POST" action="">
<div id="form_add_user_response" class="resp"></div>
<div class="box-body">
<div class="form-group">
<label for="username" class="req">User Name :</label>
<input type="text" name="userName" id="userName" placeholder="User Name" class="form-control uppercase" />
</div>
</div>
</form>
</div>
此函数用于设置输入值元素。
function editUserFunc(data_users) {
var userName = data_users.user_name;
alert(userName);
$("#userName").val(userName);}
我的功能更改为
function editUserFunc(data_users) {
var userName = data_users.user_name;
alert(userName);
var oForm = document.getElementById("form_add_pic");
var set_userName = oForm.userName;
window.location.href = "index.jsp?url=user_layout& pages=add_user_form"
}
但是我有错误
validation.js:1422 Uncaught TypeError: Cannot read property 'userName' of null
at editUserFunc (validation.js:1422)
at HTMLAnchorElement.onclick (index.jsp?url=user_layout&pages=list_users:1)
如何在另一页上调用元素表单
我已经尝试了很多次,但是都没有成功。请帮忙!

我认为,您必须将所有这些功能移入
$(document).ready(function(){
//Replace with your code
})
因为您的脚本可能位于html标记的顶部,并且在运行这些脚本时未加载这些html输入。

最后,我使用此code来获取网址栏上的参数
function getUrlQueryString(param) {
var outObj = {};
var qs = window.location.search;
if (qs != "") {
qs = decodeURIComponent(qs.replace(/\?/, ""));
var paramsArray = qs.split("&");
var length = paramsArray.length;
for (var i=0; i<length; ++i) {
var nameValArray = paramsArray[i].split("=");
nameValArray[0] = nameValArray[0].toLowerCase();
if (outObj[nameValArray[0]]) {
outObj[nameValArray[0]] = outObj[nameValArray[0]] + ";" + nameValArray[1];
}
else {
if (nameValArray.length > 1) {
outObj[nameValArray[0]] = nameValArray[1];
}
else {
outObj[nameValArray[0]] = true;
}
}
}
}
var retVal = param ? outObj[param.toLowerCase()] : qs;
return retVal ? retVal : ""
}
