Dynamic CRM 2013學習筆記（十七）JS讀寫各種類型字段方法及技巧

我們經常要對表單里各種類型的字段進行讀取或賦值，下面列出各種類型的讀寫方法及注意事項：

 

1. lookup 類型

• 清空值

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

 

• 讀取值

var state = new Array();
state = Xrm.Page.getAttribute("new_state").getValue();
if(state != null)
{
var stateText = state[0].name;
var stateId = state[0].id;
var stateType = state[0].entityType;
alert("State is: " + stateText + ", ID: " + stateId + "
of type: " + stateType);
}

特別要注意這里取出來的值，一定要加[0]，不然取不到值

 

• 賦值

var state = new Array();
state[0] = 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

 

• 讀取值

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

分別讀取顯示文本和值

另外，我們還可以用下面的方法來獲取text和value：

var sval = Xrm.Page.getAttribute("new_optionset").getText();
var sval = Xrm.Page.getAttribute("new_optionset").getValue();

• 賦值

 

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

• 讀取值

var myContactBirthday;
myContactBirthday = Xrm.Page.getAttribute("birthdate").getValue();
alert("Contact birthday is: " + myContactBirthday);
var year = myContactBirthday.getFullYear();
var month = myContactBirthday.getMonth(); // from 0 to 11
var day = myContactBirthday.getDate(); // from 1 to 31
month = month + 1;
alert("Year: " + year + ", Month: " + month + ", Day: " + day);

• 賦值

var currentDateTime = new Date();
Xrm.Page.getAttribute("new_myDate").setValue(currentDateTime);

4. Currency

• 讀取值

var myCurrencyField;
myCurrencyField = Xrm.Page.getAttribute("new_currencyfield").getValue();
alert("The value of this Currency field is: " + myCurrencyField);

• 賦值

var myCurrencyValue = 6.25;
Xrm.Page.getAttribute("new_currencyfield").setValue(parseFloat(myCurrencyValue));

5. number, text

• 讀取值

var myNumber;
myNumber = Xrm.Page.getAttribute("new_number").getValue();
alert("The number in the field is: " + myNumber);

• 賦值

Xrm.Page.getAttribute("new_text").setValue("abc");
Xrm.Page.getAttribute("new_number").setValue(123);
