How to trigger data linkage through JS

1. Usage scenarios

In the process of configuring data linkage, we usually encounter the situation that the data linkage configuration does not take effect. One of the reasons is that after we use JS to assign A value to component A, this component A is used as the condition of data linkage to trigger data linkage and link out data B, so the data linkage does not take effect. So how can we configure it?

3. Procedure

3.1 configure component a, component A, and component B to bind an action onChange event to component a. This event is triggered when the value of component a changes.

3.2 assign A value to component A through JS, and configure data linkage conditional on A in component B

As shown in the following figure:

3.3 In the action event configured by component a, the linkage update effect generated after manually updating the value is simulated by code.

The reference code is as follows:

export function onChange({ value }) {
  console.log('onChange', value);
  this.$('textField_kqs21dbs').getProps().onChange({ value: "XXX" });
  /*通过代码模拟手动更新值后产生的联动更新效果，唯一标识符为组件A的唯一标识符，XXX为给组件A赋的值*/
}
