API for Getting Component

View all component information in the report object in the dashboard:

_g().getAllWidgets();

Browser F12 developer tools to view all component information in the dashboard:

Note: When the code is added in the "after initialization" event, it is recommended to add a delay function, otherwise an error may occur because the report object is not fully created. An example is as follows:

setTimeout(function(){
     _g().getWidgetByName("comboBox0");
}, 500);

Example 1: In the dashboard, get the drop-down box widget comboBox0 on the parameter pane

_g().getWidgetByName("comboBox0");

Example 2: In the dashboard, get the drop-down box widget comboBox0 in the body

_g().getWidgetByName("comboBox0");

Example 3: In the dashboard, get the report block report0 in the body

_g().getWidgetByName("report0");

Example 4: In a dashboard, get the tab block tabpane0 in the body

_g().getWidgetByName("tabpane0");

Customize a button, get the report block when the button is clicked, and set the report block to be invisible to hide it:
