bootstrap的模态框效果挺不错，但是写起来挺麻烦，只想弹出来一段话，却要写一堆html代码，比较繁琐，找了一下，网上有封装好的js库，直接生成模态框html，不需要手写。
一、源文件
Ewin.js
(function ($) {
window.Ewin = function () {
var html = '<div id="[Id]" class="modal fade" role="dialog" aria-labelledby="modalLabel">' +
'<div class="modal-dialog modal-sm">' +
'<div class="modal-content">' +
'<div class="modal-header">' +
'<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>' +
'<h4 class="modal-title" id="modalLabel">[Title]</h4>' +
'</div>' +
'<div class="modal-body">' +
'<p>[Message]</p>' +
'</div>' +
'<div class="modal-footer">' +
'<button type="button" class="btn btn-default cancel" data-dismiss="modal">[BtnCancel]</button>' +
'<button type="button" class="btn btn-primary ok" data-dismiss="modal">[BtnOk]</button>' +
'</div>' +
'</div>' +
'</div>' +
'</div>';
var dialogdHtml = '<div id="[Id]" class="modal fade" role="dialog" aria-labelledby="modalLabel">' +
'<div class="modal-dialog">' +
'<div class="modal-content">' +
'<div class="modal-header">' +
'<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>' +
'<h4 class="modal-title" id="modalLabel">[Title]</h4>' +
'</div>' +
'<div class="modal-body">' +
'</div>' +
'</div>' +
'</div>' +
'</div>';
var reg = new RegExp("\\[([^\\[\\]]*?)\\]", 'igm');
var generateId = function () {
var date = new Date();
return 'mdl' + date.valueOf();
}
var init = function (options) {
options = $.extend({}, {
title: "操作提示",
message: "提示内容",
btnok: "确定",
btncl: "取消",
width: 200,
auto: false
}, options || {});
var modalId = generateId();
var content = html.replace(reg, function (node, key) {
return {
Id: modalId,
Title: options.title,
Message: options.message,
BtnOk: options.btnok,
BtnCancel: options.btncl
}[key];
});
$('body').append(content);
$('#' + modalId).modal({
width: options.width,
backdrop: 'static'
});
$('#' + modalId).on('hide.bs.modal', function (e) {
$('body').find('#' + modalId).remove();
});
return modalId;
}
return {
alert: function (options) {
if (typeof options == 'string') {
options = {
message: options
};
}
var id = init(options);
var modal = $('#' + id);
modal.find('.ok').removeClass('btn-success').addClass('btn-primary');
modal.find('.cancel').hide();
return {
id: id,
on: function (callback) {
if (callback && callback instanceof Function) {
modal.find('.ok').click(function () { callback(true); });
}
},
hide: function (callback) {
if (callback && callback instanceof Function) {
modal.on('hide.bs.modal', function (e) {
callback(e);
});
}
}
};
},
confirm: function (options) {
var id = init(options);
var modal = $('#' + id);
// modal.find('.ok').removeClass('btn-primary').addClass('btn-success');
modal.find('.cancel').show();
return {
id: id,
on: function (callback) {
if (callback && callback instanceof Function) {
modal.find('.ok').click(function () { callback(true); });
modal.find('.cancel').click(function () { callback(false); });
}
},
hide: function (callback) {
if (callback && callback instanceof Function) {
modal.on('hide.bs.modal', function (e) {
callback(e);
});
}
}
};
},
dialog: function (options) {
options = $.extend({}, {
title: 'title',
url: '',
width: 800,
height: 550,
onReady: function () { },
onShown: function (e) { }
}, options || {});
var modalId = generateId();
var content = dialogdHtml.replace(reg, function (node, key) {
return {
Id: modalId,
Title: options.title
}[key];
});
$('body').append(content);
var target = $('#' + modalId);
target.find('.modal-body').load(options.url);
if (options.onReady())
options.onReady.call(target);
target.modal();
target.on('shown.bs.modal', function (e) {
if (options.onReady(e))
options.onReady.call(target, e);
});
target.on('hide.bs.modal', function (e) {
$('body').find(target).remove();
});
}
}
}();
})(jQuery);
二、调用方法
首先引入js文件
1.仅包含确定按钮的提示框
Ewin.alert({message: "提示语句"});
如果需要在弹出框点击确定后再执行一些方法：
Ewin.alert({message: "提示语句"]}).on(function (e) {
if (e) {
//TODO
}
});
2.包含确定取消的提示框
Ewin.confirm({ message: "确认要删除选择的数据吗？" }).on(function (e) {
if (!e) {
//点击取消按钮
}else{
//点击确定按钮
}
});
