Extensions parameters allow to initialize and set parameters that are relative to an Extension, for example:
- Parameters for the printing.
- Header of a report that are set once only.
The script should provide a function settingDialog() that is called when the user click on the Set Parameters on the Manage Apps dialog.
The function settinDialog() should:
- Read the existing setting with the Banana.document.getScriptSettings();
- Request user to enter the information
- Set the modified values with the function Banana.document.setScriptSettings(paramToString);
The JSon text will be saved within the accounting file.
function settingsDialog() { var param = initParam(); var savedParam = Banana.document.getScriptSettings(); if (savedParam.length > 0) { param = JSON.parse(savedParam); } param = verifyParam(param); param.isr_bank_name = Banana.Ui.getText('Settings', texts.param_isr_bank_name, param.isr_bank_name); if (param.isr_bank_name === undefined) return; var paramToString = JSON.stringify(param); Banana.document.setScriptSettings(paramToString); }
the function Exec() should then read the setting.
It is a good practice to check and verify if the setting are valid.
function printDocument(jsonInvoice, repDocObj, repStyleObj) { var param = initParam(); var savedParam = Banana.document.getScriptSettings(); if (savedParam.length > 0) { param = JSON.parse(savedParam); param = verifyParam(param); } printInvoice(jsonInvoice, repDocObj, repStyleObj, param); }
