Can i place a string value in thymeleaf link instead of id and without first listing the database table contents. Like this
<a th:href="#{particularList/{type}(type=lcd)}">
In razor mvc helper, I can provide a querystring to ActionLink as a name value pair e.g. new {x = "something"}
How can I pass a querystring which is raw data and not name value e.g. if I have abc, I want it to show as <a href="mylink?something"> instead of <a href="mylink?x=something">
You can use Url.Action html helper method along with the anchor tag markup.

I am learning Struts2 and have the following question on submitting a form with Jquery serialize. I have an action class where I have an object called Policy and the policy class has set of fields as shown below. With jquery ajax I want to set a json string in my Action class and would like to deserialize it to an object.
How much ever I try, I am not able to set the string I defined in my action class. Below is the code
Class CassPolicy{
String policyNumber;
String name;
//getsets for members
}
Action:
Class PolicyAction{
String cassPolicyString;
CassPolicy cassPolicy = new CassPolicy();
//getsets for members
String save(){
//In save method I want to convert the policyString to policy object
//policyString always returns null
}
}
JSP:
$.ajax({
url:PolicyAction.action,
type:'post',
data:$("#policyForm").serialize(),
async:true,
success:function(data){
}
});
<s:form id="policyForm">
<s:textfield name="cassPolicy.policyNumber" label="policyNumber"></s:textfield>
<s:textfield name="cassPolicy.name" label="name"></s:textfield>
</s:form>
I even tried in ajax something like data:{cassPolicyString:$("#policyForm).serialize()}
Can someone help me point to the right direction or what is the right way to achieve my task?
I figured it out finally.. The issue is form serialize does not give a json format. I used the code in below link to serialize my form as json object and added a interceptor ref element to my action in struts.xml which finally assigned my form values to cassPolicy object.
Convert form data to JavaScript object with jQuery
When I return a JSon value, i simply want to put a string inside an existing div
EDIT: Let me Rephrase this: I want my MVC controller to return a JSON object to the UpdateTarget specified in the MVC AJAX call. Instead of returning "content".
Assume your JSON String looks like this:
var jobj = '{"name":"value"}';
and you have a div on the HTML with id mycontentdiv then
document.getElementById("mycontentdiv").innerHTML = jobj.name;
will take the "value" and place it in the div.
Without further details it is difficult to be more specific.
ASP.NET MVC can generate HTML elements using HTML Helpers, for example #Html.ActionLink(), #Html.BeginForm() and so on.
I know I can specify form attributes by creating an anonymous object and pass that object for the (fourth in this case) htmlAttributes parameter where specifying an id for the element:
Html.BeginForm("Foo", "Bar", FormMethod.Post, new { id = "MyForm"})
But what about the class attribute? Obviously this does not work:
Html.BeginForm("Foo", "Bar", FormMethod.Post, new { class = "myclass"})
As that just throws random syntax errors when my view is requested, because it expects something else after encountering the C# keyword class.
I've also tried:
new { _class = "myclass"}
and
new { class_ = "myclass"}
But they also did not work, as the underscores get replaced by dashes.
I know that I can just as well write the HTML elements by hand or wrap the form inside a <div class="myClass">, but I'd still be interested to know how it is supposed to be done.
In order to create an anonymous type (or any type) with a property that has a reserved keyword as its name in C#, you can prepend the property name with an at sign, #:
Html.BeginForm("Foo", "Bar", FormMethod.Post, new { #class = "myclass"})
For VB.NET this syntax would be accomplished using the dot, ., which in that language is default syntax for all anonymous types:
Html.BeginForm("Foo", "Bar", FormMethod.Post, new with { .class = "myclass" })
Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.
If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.
