Your Server end :
ViewBag.Js = "alert()";
Your CsHtml Page :
<script type='text/Javascript'>
#Html.Raw(#ViewBag.Js);
</script>;

Access Java / Servlet / JSP / JSTL / EL variables in JavaScript
(5 answers)
Closed 3 years ago.
I have a controller which returns a ModelAndView object
return new ModelAndView("operatorDetail", model);
I can then access the elements in the model object from my JSP page like this
<c:if test="${not empty operator and operator.regionId eq item.regionId}"
my question is, is there a way I can access those elements in my javascript code ?.
I thought about putting those values in an input element in HTML and make it hidden and access their values, but is there a more practical way?
thank you.
Yes of course you can have something like this. Declare var in jsp
<c:set var="yourJspVar" scope="session" value=" your object"/>
and in java-script set variable like
<script>
var jsVar = '${yourJspVar}';
alert(jsVar);
</script>

Get the values from the "GET" parameters (JavaScript) [duplicate]

I'm having an issue with my codes concerning the transfer of information from one page to another using the url as shown below:
window.location.href ="form.html?uname="+uname;
The value is displaying in the url box but when I try to display it on the form.html page using the following code:
window.onload = function ()
{
var name = document.getElementById("uname");
alert(name);
}
The alert keep displaying null.
What is the issue because after an hour of troubleshooting, I can't seem to figure it out.
Is the null being displayed in the alert box means that the value is not being retrieve from the url?
Thanks in advance.
document.getElementById('uname')
looks for an HTML element with the corresponding id. What you probably want to do is:
alert(uname)

JavaScript property access: dot notation vs. brackets?
(17 answers)
Closed 7 years ago.
i have Javascript object as below.
How can i get value for SERIAL#, like i can retrieve *.INST_ID or *.INSTANCE.
how can i escape # and get the value required.
So far i have tried SERIAL#23% but none helped so far.
var t = {"INST_ID":"1","INSTANCE":"xina","SID":"27","SERIAL#":"48810", "PROGRAM":"Perl#app01"}
console.log(kSess.SERIAL%23); gives syntax error
I am parsing variable "t"
This data is coming from java code, so there is nothing much i can do to change SERIAL# to something else
Any idea?
Try to retrieve the value like this...
t["SERIAL#"]; // will return you the value..
Store it somewhere or play with it as you like. :)

How do I reference a JavaScript object property with a hyphen in it?
(11 answers)
Closed 8 years ago.
I have a field sent by SERVICE which is having hypen in it. Eg., first-name (As JSON object)
But when I try to get the value of that field through the jsp. I am getting a script error.
Please let me know how to access the hypen also in this?
var nameList = msg.RESPONSE.DATA.NAME-LIST;
The above way when I try to access it is throwing script error
A variable or property name with an hyphen is indeed wrong in javascript (Jquery).
However, you can access the "problematic" property like this :
var nameList = msg.RESPONSE.DATA["NAME-LIST"];
I would recommend to rename the property(ies)
without hyphen if you control the content of this response
