V8 Function List-Front End ​

Introduction ​

• The front-end V8 engine code and the server-side V8 programming language are Javascript syntax.
• Front-end V8 engine supports full ES6 syntax
• The front-end V8 engine integrates many functions to directly call the back-end interface through http, which is the same as V8.Post() writing the corresponding interface address.
• The front-end V8 engine code is executed at the front-end. If the server-end low-code platform general addition, deletion, modification and query interface is directly called, the front-end V8 event will not be executed (the server-end V8 event will be executed).

V8.Form ​

Access current form field values Example: var name = V8.Form.UserName; If it is a drop-down box component and the binding display field is set, it can be: V8.Form. The field name. Display Fields

V8.OldForm ​

Access the field value before the current form is modified. Example: var oldName = V8.OldForm.UserName;

V8.FormSet ​

Assign a value to the current form field Example: V8.FormSet('UserName', 'Zhang San'); You can also use the regular js writing method (but it may not take effect in some special cases):V8.Form.UserName = 'Zhang San ';

V8.Field ​

Access the current form field properties Example: var isReadonly = V8.Form.UserName.Readonly;// UserName whether the field is currently read-only Contains properties: Name, Label, Config, Data (binding data source), Readonly, Visible, Placeholder, and so on

V8.FieldSet ​

Assign a value to the current form field property Example: V8.FieldSet('UserName', 'Readonly', false);// Set the UserName field to read-only

V8.FormOutAction ​

Get the type of leaving the form, which can be used as a judgment in V8 engine code after leaving the form and submitting the form. Possible values: Update/Insert/Close/Delete

V8.FormOutAfterAction ​

Get the type after leaving the form, which can be used to leave the form/submit the V8 engine code after the form, possible values: Insert/Update/View/Close

V8.FormSubmitAction ​

Form submission type (Insert/Update/Delete), you can assign V8.Result = false in the "V8 engine code before form submission" to prevent form submission.

V8.FormMode ​

get the mode of the current Form opening, possible values: Add (new), Edit (edit), View (preview)

V8.LoadMode ​

the loading mode of the current Form is either empty or the value is Design(string, design mode). pay special attention to some events. if V8.FieldSet is used to change the field properties, it is necessary to judge that V8.LoadMode = = 'Design' will not be executed, otherwise the field properties will be saved persistently after the form design is saved.

V8.TableRowId ​

Get the Id of the current Form, or use V8.Form.Id

V8.KeyCode ​

keyboard event V8 can get the code value of the keyboard, such as the Enter key corresponding to 13

if(V8.KeyCode == 13){
    V8.Tips('您已经按了Enter键！');
}

V8.TableId, V8.TableName ​

Obtain the ID and Name of the current DIY table

V8.EventName ​

The name of the front-end V8 event, which is relatively easy to use in the global V8 engine code. Possible values: FormTemplateEngine: Form Template Engine TableTemplateEngine: Table Template Engine OpenTableBefore: Pop-up Form Pre-Event OpenTableSubmit: Pop-up form submission event FieldOnKeyup: Text Box Keyboard Events FormOut: Leave form event (refers to after form submission) FormSubmitBefore: Pre-Form Submission Events FormIn: Enter Form Event FieldValueChange: Field Value Change Event BtnFormDetailRun: Details Button V8 Button V8BtnLimit: whether the V8 button shows an event V8BtnRun:V8 button execution event TableRowClick: Table row click V8 event PageTab: Multi Tab V8 Event WFNodeEnd: Process Node End V8 Event WFNodeStart: Process Node Start V8 Event

V8.CurrentToken ​

Current login identity token

V8.TableModel ​

Obtain the object of the current table, which contains table information such as Id and Name.

V8.ThisValue ​

Access the value object selected by the drop-down box, such as V8.ThisValue.Id

V8.Tips ​

pop-up message prompt in the lower right corner, usage: V8.Tips(msgContent, true/false, time) msgContent to message content true is a success message (disappears after 1 second),false is an error message (disappears after 5 seconds) Time can be passed into the prompt box for how many seconds before it disappears.

V8.CurrentUser ​

Access current login user information Example: V8.CurrentUser.Id/Name/Role/Dept and so on

V8.Post ​

//发起ajax请求，常规用法，自带token，默认Form Data参数格式（非Request Payload）
V8.Post('api url', { Id : 1 }, function(result){
    if(result.Code == 1){ ... }
})
//完整用法
V8.Post({
  url : '',//接口地址，必传。
  data : {}, //接口参数
  dataType : 'json', //默认空（Form Data），可选json（Request Payload）
  header : {}, //可选参数
  success : function(result){ }, //请求成功的回调函数，常用参数。
  fail : function(result){ }, //请求失败的回调函数，如接口报错404、500，可选参数，也可传入error，与fail一致。
});

V8.Get ​

Initiate an ajax request, V8.Get('api url', {}, function(result){})

V8.ChineseToPinyin(chinese, fullPyLen, type) ​

Chinese to Pinyin fullPyLen: 2 (default), the first few words are all pinyin; type : 1 hump (default),2 all uppercase, 3 all lowercase

V8.RefreshTable({ _PageIndex : -1 }) ​

Refresh the table data list. If -1 is passed in_PageIndex, it means to jump to the last page. It is generally used to refresh the current table with more buttons on pages, more buttons on rows, etc. Note that unlike [V8.TableRefresh], it refreshes the sub-table in the current main form (function naming will be optimized in the future).

V8.Router.Push(url): Page Jump ​

V8.Window.Open(url): Open a new page ​

V8.OpenForm(formModel, type) ​

Open the form, type:'View'/'Edit'/'Add', as in the [Row More V8 button] event: V8.OpenForm(V8.Form, 'Edit')

V8.SearchSet ​

Tabs Set search criteria, for example: V8.SearchSet({FieldName : value, FieldName2 : value}) 2024-12-14 new can pass in _Where condition, usage: V8.SearchSet([{ Name : 'Age', Value : 18, Type : '>' }]);

V8.SearchAppend ​

Tabs Append search criteria, for example: V8.SearchAppend({FieldName : value, FieldName2 : value}) 2024-12-14 new can pass in _Where condition, usage: V8.SearchAppend([{ Name : 'Age', Value : 18, Type : '>' }]);

V8.AppendSearchChildTable [V8.OpenTableSetWhere is recommended]] ​

Specify search criteria for the table in the [Pop-up Pre-Event V8 Code] of the pop-up table, for example: V8.AppendSearchChildTable(V8.Field.XuanzeGLSP, { ShangpinLXZ: '1'});

V8.OpenTableSetWhere ​

Specify search criteria for the table in the [Pop-up Pre-Event V8 Code] of the pop-up table For example: V8.OpenTableSetWhere(V8.Field.XuanzeGLSP, [{ Name : 'ShangpinMC', Value: 'Commercial Drink Maker ', Type : 'Like' }]);

V8.IsNull(value): Determine if a value is empty ​

If the value is null, undefined, ''(empty string), 'null'(null string), 'undefined'(undefined string), return true

The parent table operates on the child table: ​

V8.TableSearchAppend(V8.Field.子表Name, {FiedlName : value, FieldName2 : value})

V8.TableSearchSet(V8.Field.子表Name, {FiedlName : value, FieldName2 : value})

V8.TableRefresh(V8.Field.子表Name, { _PageIndex : -1 })
_PageIndex传入-1表示跳转到最后一页。（注意与【V8.RefreshTable】不同的是它一般是用于模块引擎中行更多按钮、页面更多按钮刷新当前表格，将来会优化函数命名）。
