Question

如何修改自动调整大小插件，以便可以将选项autoresize_max_height设置为原始高度的百分比？

E.g

var defaults = {
    height: 500,
    autoresize_max_height: "150%",
}

$(selectTinyMce).tinymce(defaults);

$(selectTinyMceSmall).tinymce($.extend(true, {}, defaults, {
    height: 200
}));

$(selectTinyMceLarge).tinymce($.extend(true, {}, defaults, {
    height: 1000
}));

        }
    });

    // Register plugin
    tinymce.PluginManager.add('autoresize', tinymce.plugins.AutoResizePlugin);
})();

注意：我添加了if (myHeight < ed.getParam("height"))以确保高度不会低于原始高度，以便完整编辑器可以点击＆＃34;默认情况下，它有很多填充。

您可以使用配置的heigth信息来计算插件中的autoresize_max_height值：

// Define maximum height
var percentage = parseInt(ed.getParam('autoresize_max_height', 0)); // the value here is a percentage value without the "%"

t.autoresize_max_height = ed.getParam('height') || 500; // 500 as default if height has not been set
// apply the percentage
t.autoresize_max_height = parseInt(t.autoresize_max_height * (percentage/100));

tinymce autoresize插件使用原始高度的百分比
