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>' + '<div><div>' + '<div>' + '<a data-dismiss="modal">×</a>' + '<h4>'+PARAMS.title+'</h4></div>' + '<div>'+PARAMS.content+'</div>' + '<div>'; if(type=='confirm'){ html += '<button>'+PARAMS.cancelbtn+'</button>'; } html += '<button>'+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> <button>确认框</button> <button>提示框</button> </div> </body> <script src="https://www.jb51.net/jquery/jquery.min.js"></script> <script src="https://www.jb51.net/bootstrap/bootstrap.min.js"></script> <script src="https://www.jb51.net/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。
