扩展 jquery ui 对话框(添加更多选项) [英] extend jquery ui dialog (add more options)

问题描述

如何为 jQuery 对话框创建和添加新选项?例如:我喜欢通过设置选项可以控制标题栏的显示或关闭按钮的显示.

how I can create and add new options for jQuery dialog? for example: I like that through on the setting options can control the display of title bar or display the close button.

脚本是这样的:

$("#message").dialog({
  showTitle:false,     //new option (hide Title bar)
  showCloseButton:true //new option (show close button)
  modal:true...        //other options
})

推荐答案

这比我在评论中表达的要容易一些.

It's a little easier than I expressed in my comment.

// store old method for later use
var oldcr = $.ui.dialog.prototype._create;
// add the two new options with default values
$.ui.dialog.prototype.options.showTitlebar = true;
$.ui.dialog.prototype.options.showClosebutton = true;
// override the original _create method
$.ui.dialog.prototype._create = function(){
    oldcr.apply(this,arguments);
    if (!this.options.showTitlebar) {
       this.uiDialogTitlebar.hide();
    }
    else if (!this.options.showClosebutton) {
       this.uiDialogTitlebar.find(".ui-dialog-titlebar-close").hide();
    }
};

// this is how you use it
$("<div />").dialog({
    showClosebutton: false
});
// or
$("<div />").dialog({
    showTitlebar: false
});

显然，如果标题栏被隐藏，关闭按钮也将被隐藏，因为它是标题栏的一部分.

Obviously, if the titlebar is hidden, the close button will also be hidden since it is part of the titlebar.
