Question

在另一个旁边添加按钮的最聪明方法是什么：＆＃34;新建，转移，分享＆＃34;？

是否有可以创建自定义操作的位置？或者我是否需要通过JSLink覆盖？

Answer 1

至少我解决了这个问题。我的代码有点硬编码，但我会对它进行排序。我添加了一个＆＃34; mutationobserver＆＃34;发现OOTB按钮＆＃34;分享＆＃34;被禁用或启用。如果启用，则仅选择一个项目。然后我在JSOM中做了额外的检查，看看有多少项被选中，这取决于我用JQUERY显示和隐藏某些按钮。

window.SIMON.Library = {
editFunction: function () {
    var ctx = new SP.ClientContext.get_current();

    var item = SP.ListOperation.Selection.getSelectedItems(ctx)[0];
    var list = ctx.get_web().get_lists().getById(SP.ListOperation.Selection.getSelectedList(ctx));
    ctx.load(list, 'DefaultEditFormUrl');
    ctx.executeQueryAsync(function () {
        var editFormUrl = list.get_defaultEditFormUrl() + "?ID=" + item.id;
        openInDialog(800, 600, false, true, false, editFormUrl);



    }, function (sender, args) {
        console.log(args.get_message());
    });





},

displayFunction: function () {
    var ctx = new SP.ClientContext.get_current();

    var item = SP.ListOperation.Selection.getSelectedItems(ctx)[0];
    var list = ctx.get_web().get_lists().getById(SP.ListOperation.Selection.getSelectedList(ctx));
    ctx.load(list, 'DefaultDisplayFormUrl');
    ctx.executeQueryAsync(function () {
        var viewFormUrl = list.get_defaultDisplayFormUrl() + "?ID=" + item.id;
