保存隐藏字段时XRM.Page API调用的差异

Question

I have a function in JS which is triggered as event handler when user picks new option from dropdown.

function providerMarketingListOnChangeEventHandler() {
    console.log("Provider marketing list option changed!");
    // Get selected provider m. list option value
    var selectedMarketingListValue = $(this).find("option:selected").text();

    // Use XRM.Page API to set hidden attribute value to the value of the selected option
    // Option 1 - this?   
    // Xrm.Page.getAttribute("new_marketinglist_provider").setValue(selectedMarketingListValue);

    // Option 2 - or this?     
    // Xrm.Page.data.entity.attributes.get("new_marketinglist_provider").setValue(selectedMarketingListValue);
    Xrm.Page.data.entity.save();
}

Dropdown is loaded as WebResource on CRM 2015 form. The entity for this form has field named " new_marketinglist_provider ", but it has to be hidden on the form.

Now I am trying to save selected option text to this field, and save entity. I have two Xrm.Page API calls, but which one should I use? (Please see comments in function.)

Answer 1

try this :

Xrm.Page.getAttribute("new_marketinglist_provider").setValue(selectedMarketingListValue);

Xrm.Page.getAttribute("new_marketinglist_provider").setSubmitMode("always");
