How do I get to the value of a page custom field in the background of a Mvcsheet form page?

Problem:

<asp:hiddenfield id= "test" runat= "Server"/> in the foreground add such a hidden element, mvcsheet form page, how to get the value in the background, the direct use of test.value has been empty.

the foreground passes a series of judgment processing to write this value, need to obtain in the background, then processing data.

existing processes are on-line, do not want to add fields, and then publish process processing.

Is there any good way to deal with it?

Workaround :

1. You can first change the HiddenField control to a textbox to check if your JS has paid the value to the server control.

Note: when the foreground JS assigns a value to the server control, the ID is obtained by the <%= ID name. ClientID%>

2. May be loading the background method when the foreground JS has not given the parameter value up,

can be processed in a different mode, through the foreground JS Invoke Background method

Add custom toolbar button methods to trigger background events

$. Mvcsheet.addaction ({

Action: "Testaction",//Execute background method name

Icon: "Fa-print",//button icon

Text: "Background event",//button name

Datas: ["{Selectuser}"],//parameters, multiple parameters "{Param1}", "Param2" ...

Onaction:function () {

/*

The custom button execution event, if NULL, calls $. Mvcsheet.action performing a background method

if It is not NULL, then the method will be executed here, you need to post to the background or write the front-end logic

*/

//},

Onactiondone:function (e) {

Triggers when a background method call completes

The following is the output of the background value to the front-end control

if (e) {

$. Mvcsheetui.setcontrolvalue ("code", E.code);

$. Mvcsheetui.setcontrolvalue ("Mvcname", e.name);

}

},

Postsheetinfo:true//Whether the form data is submitted, if false, the data of the form is not returned

});
