How to achieve automatic two-column view如何实现自动两栏查看

[aleo-yu]

I use gpt to make a single column double column view switching script, but I hope that when opening pdf, the default open is double column view, how to modify the code to achieve this function

/**
 * Toggle Single / Double Column in PDF Reader
 * @author YourName
 * @usage 
 * @link https://github.com/windingwind/zotero-actions-tags
 */
const Zotero = require("Zotero");
const Zotero_Tabs = require("Zotero_Tabs");

if (!item) { return; }

// 获取当前阅读器实例
const reader = Zotero.Reader.getByTabID(Zotero_Tabs.selectedID);

if (!reader) { return; }

// 获取阅读器的内部实例
const internalReader = reader._internalReader;

if (!internalReader) { return; }

// 获取当前的视图模式
const currentViewMode = internalReader._lastView._iframeWindow.PDFViewerApplication.pdfViewer.spreadMode;

// 切换视图模式
if (currentViewMode === 0) {
    // 切换到双栏视图
    internalReader._lastView._iframeWindow.PDFViewerApplication.pdfViewer.spreadMode = 1;
} else {
    // 切换到单栏视图
    internalReader._lastView._iframeWindow.PDFViewerApplication.pdfViewer.spreadMode = 0;
}

// 重新渲染视图
internalReader._lastView._iframeWindow.PDFViewerApplication.pdfViewer.update();
