Dynamic CRM 2013 Learning Notes (17) JS Read and write various types of field methods and techniques

We often have to read or assign the various types of fields in the form, and the following lists the various types of reading and writing methods and considerations:

1. Lookup type

• Empty value

var state = Xrm.Page.getAttribute ("new_state");
if null)
{
Xrm.Page.getAttribute ("new_state"). SetValue (null);
}

• Read value

var New Array ();
State = Xrm.Page.getAttribute ("new_state"). GetValue ();
if null)
{
var statetext = state[0]. name;
var stateid = state[0].id;
var stateType = State[0].entitytype;
Alert ("" + statetext + "" + Stateid + "
of type: " + stateType);
}

Pay special attention to the value taken here, must add [0], or not get the value

• Assign value

var New Array ();
New Object ();
State[0].id = "{ba0762e4-64d2-e111-909e-00155d6c871a}";
State[0]. name = "New York";
State[0].entitytype = "new_state";
Xrm.Page.getAttribute ("new_state"). SetValue (state);

2. Option Sets

• Read value

var sval = Xrm.Page.getAttribute ("new_optionset"). Getselectedoption (). text;
var sval = Xrm.Page.getAttribute ("new_optionset"). Getselectedoption (). value;

Read display text and values, respectively

In addition, we can use the following method to get the text and value:

var sval = Xrm.Page.getAttribute ("new_optionset"). GetText ();
var sval = Xrm.Page.getAttribute ("new_optionset"). GetValue ();

• Assign value

function Setosvalue (Osname, Oslabel)
{
var options = Xrm.Page.getAttribute (osname). GetOptions ();
 for (i = 0; i < options.) length; i++)
{
if (Options[i].text = = Oslabel)
Xrm.Page.getAttribute (Osname). SetValue (Options[i].value);
}
}

3. Datetime

• Read value

var mycontactbirthday;
Mycontactbirthday = Xrm.Page.getAttribute ("birthdate"). GetValue ();
Alert ("" + mycontactbirthday);
var year = Mycontactbirthday.getfullyear ();
var //From 0 to one
var //from 1 to
Month = month + 1;
Alert ("+ year +""+ month +""+ Day");

• Assign value

var New Date ();
Xrm.Page.getAttribute ("new_mydate"). SetValue (Currentdatetime);

4. Currency

• Read value

var mycurrencyfield;
Mycurrencyfield = Xrm.Page.getAttribute ("new_currencyfield"). GetValue ();
Alert ("" + Mycurrencyfield);

• Assign value

var mycurrencyvalue = 6.25;
Xrm.Page.getAttribute ("new_currencyfield"). SetValue (parsefloat(mycurrencyvalue));

5. Number, text

• Read value

var mynumber;
MyNumber = Xrm.Page.getAttribute ("new_number"). GetValue ();
Alert ("" + mynumber);

• Assign value

Xrm.Page.getAttribute ("new_text"). SetValue ("ABC");
Xrm.Page.getAttribute ("new_number"). SetValue (123);
