I. Overview
1.1 Problem description
Sometimes we want to hide some widgets of the parameter pane when switching the sheet. This article takes hidig the query button as an example to illustrate the implementation steps. The final effect is as follows:
1.2 Implementation ideas
In the Loading End event of the reporting page, bind a click event to a sheet and determine whether there are widgets in the sheet that need to be hidden. In the click event, the widgets are hidden or displayed by code.
II. Operation steps
2.1 Open the template
Open the report %FR_HOME%\webapps\webroot\WEB-INF\reportlets\GettingStartedEN.cpt and create a new sheet named sheet2, as shown below:
2.2 Add event
Click Template > Web Attributes > Data Entry Settings (choose according to the preview mode), check Indivisually set for the template, and then add a Loading End event, as shown in the figure below.
Note: Since the Loading End event is added here, you need to click the query button to let the report to complete the loading process before the code is effective. If you don't want to click the query button before realizing the effect, you can uncheckDisplay Nothing Before Query in the attribute settings of the parameter pane.
The JavaScript code in the Loading End event is as follows:
$(".fr-sheetbutton-container").click(function() //When switching sheets
{
var a = contentPane.$contentPane.data('TabPane').tabBtns[contentPane.selectedIndex].options.name; //Get the name of the current sheet
if(a == "sheet2") {
contentPane.parameterEl.getWidgetByName("widget3").setVisible(false); //Hide the query button. widget3 is the name of the query button
} else {
contentPane.parameterEl.getWidgetByName("widget3").setVisible(true); //Display query button
}
});
2.3 Preview effect
Save the template, click the Data Entry Preview, click the query button, and then switch the sheet to see the above effect.
Note: Mobile terminal is not supported.
