这篇文章主要为大家详细介绍了基于bootstrap风格的弹框插件，适用于确认框、提示框，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
自己写的一款基于bootstrap风格的弹框插件，暂时只有确认框、提示框。后续功能扩展、bug修改再更新。
;(function($){
//默认参数
var PARAMS;
var DEFAULTPARAMS =
{
width: 500,
title: '提示消息',
content: '',
okbtn: '确定',
cancelbtn: '取消',
headerBackground: 'info',
vbackdrop: 'static', //默认点击遮罩不会关闭modal
vkeyboard: true, //按esc关闭modal
confirmFn: new Object,
cancelFn: new Object
};
$.dialog = {
confirm: function(params){
$.dialog.initParmas(params);
$.dialog.Show('confirm', function(e){
if($.isFunction(PARAMS.confirmFn)){
PARAMS.confirmFn(e);
}
},
function(f){
if($.isFunction(PARAMS.cancelFn)){
PARAMS.cancelFn(f);
}
});
},
alert: function(params){
$.dialog.initParmas(params);
$.dialog.Show('alert', function(e){
if($.isFunction(PARAMS.confirmFn)){
PARAMS.confirmFn(e);
}
}, null);
},
Show: function(type, confirmCaller, cancelCaller){
var html = '<div class="modal fade" id="tipModal">'
+ '<div class="modal-dialog" style="width:'+PARAMS.width+'px"><div class="modal-content">'
+ '<div class="modal-header header_'+PARAMS.headerBackground+'">'
+ '<a class="close" data-dismiss="modal">×</a>'
+ '<h4 class="modal-title text-center">'+PARAMS.title+'</h4></div>'
+ '<div class="modal-body text-center body_content">'+PARAMS.content+'</div>'
+ '<div class="modal-footer">';
if(type=='confirm'){
html += '<button class="btn btn-default" id="btnCancel">'+PARAMS.cancelbtn+'</button>';
}
html += '<button class="btn btn-primary" id="btnOk">'+PARAMS.okbtn+'</button>';
html += '</div></div></div></div>';
$('body').append(html);
$('#tipModal').modal({backdrop:PARAMS.vbackdrop,keyboard:PARAMS.vkeyboard});
$.dialog.setDialogEvent(type, confirmCaller, cancelCaller);
},
initParmas: function(params){
if(params!= undefined && params!= null){
PARAMS = $.extend({}, DEFAULTPARAMS, params);
}
},
setDialogEvent: function(type, confirmCaller, cancelCaller){
switch(type){
case 'confirm':
$("#btnOk").click(function(){
$('#tipModal').modal('hide');
$('#tipModal').on('hidden.bs.modal', function(){
$('#tipModal').remove(); //要先remove modal
if($.isFunction(confirmCaller)){
confirmCaller(true);
}
});
});
$("#btnCancel").click(function(){
$('#tipModal').modal('hide');
$('#tipModal').on('hidden.bs.modal', function(){
$('#tipModal').remove();
if($.isFunction(cancelCaller)){
cancelCaller(false);
}
});
});
break;
case 'alert':
$("#btnOk").click(function(){
$('#tipModal').modal('hide');
$('#tipModal').on('hidden.bs.modal', function(){
$('#tipModal').remove();
if($.isFunction(confirmCaller)){
confirmCaller(true);
}
});
});
break;
};
$('#tipModal').on('hidden.bs.modal', function(){
$('#tipModal').remove();
});
$("#tipModal .close").click(function(){
$('#tipModal').on('hidden.bs.modal', function(){
$('#tipModal').remove();
});
});
//设置窗口可拖动
$('#tipModal .modal-header').Draggable($('#tipModal .modal-dialog'));
}
};
dialogConfirm = function(params){
$.dialog.confirm(params);
};
dialogAlert = function(params){
$.dialog.alert(params);
};
})(jQuery);
//拖动层
;(function($){
$.fn.extend({
Draggable: function(objMoved){
return this.each(function(){
//鼠标按下时的位置
var mouseDownPosiX, mouseDownPosiY;
//obj的初始位置
var objPosiX, objPosiY;
//鼠标移动的距离
var tempX, tempY;
//移动的对象
var obj = $(objMoved)==undefined ? $(this): $(objMoved);
//是否处于移动状态
var status = false;
$(this).mousedown(function(e){
status = true;
mouseDownPosiX = e.pageX;
mouseDownPosiY = e.pageY;
objPosiX = obj.css("left").replace("px", "");
objPosiY = obj.css("top").replace("px", "");
}).mouseup(function(){
status = false;
});
$(document).mousemove(function(e){
if(status){
tempX = parseInt(e.pageX) - parseInt(mouseDownPosiX) + parseInt(objPosiX);
tempY = parseInt(e.pageY) - parseInt(mouseDownPosiY) + parseInt(objPosiY);
obj.css({ "left": tempX + "px", "top": tempY + "px" });
}
//判断是否超出窗体
//计算出弹出层距离右边的位置
var dialogRight = parseInt($(window).width())-(parseInt(obj.css("left"))+parseInt(obj.width()));
var dialogBottom = parseInt($(window).height())-(parseInt(obj.css("top"))+parseInt(obj.height()));
var maxLeft = $(window).width()-obj.width();
var maxTop = $(window).height()-obj.height();
if(parseInt(obj.css("left"))<=0){
obj.css("left","0px");
}
if(parseInt(obj.css("top"))<=0){
obj.css("top","0px");
}
if(dialogRight<=0){
obj.css("left",maxLeft+'px');
}
if(dialogBottom<=0){
obj.css("top", maxTop+'px');
}
}).mouseup(function(){
status = false;
}).mouseleave(function(){
status = false;
});
});
}
});
})(jQuery)
html页面中调用：
<body>
<div class="box">
<button class="btn btn-default" id="btn_confirm">确认框</button>
<button class="btn btn-default" id="btn_cancel">提示框</button>
</div>
</body>
<script src="jquery/jquery.min.js"></script>
<script src="bootstrap/bootstrap.min.js"></script>
<script src="js/dialog.js"></script>
<script type="text/javascript">
$(function(){
$("#btn_confirm").click(function(){
dialogConfirm({
width: 500,
content: '确定要删除吗?',
headerBackground: 'info',
vbackdrop: true, //默认点击遮罩不会关闭modal
vkeyboard: true, //按esc关闭modal
confirmFn: function(e){
dialogAlert({
width: 300,
content: 'true',
headerBackground: 'success',
vbackdrop: 'static', //默认点击遮罩不会关闭modal
vkeyboard: true //按esc关闭modal
});
},
cancelFn: function(f){
alert(f);
}
})
});
$('#btn_cancel').click(function(){
dialogAlert({
width: 300,
content: '删除成功!',
headerBackground: 'error',
vbackdrop: 'static', //默认点击遮罩不会关闭modal
vkeyboard: true, //按esc关闭modal
});
});
});
</script>
感觉写的不是很好，后面修改了或者扩展了功能再更新。源码会上传到文件。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持脚本之家。 |
