自己封装的一个纯div+css样式弹出泡泡消息框

也许很多框架都自带了这样的弹出泡泡框，但我没接触过，现在需要用，于是便自己封装了一个，虽然还不完美，，但已经可以用了。这个小控件可以重定义样式，通过传递配置参数，或修改默认配置参数都可以进行样式调整。不管怎么说，就当是练手，或给新人提供一个参考学习的机会也行吧/* * js 对象合并 */function extend(newObj, defaultObj) {var result = {};for (var p in defaultObj) {result[p] = defaultObj[p];if (typeof (defaultObj[p]) == " function ") {defaultObj[p]();} else {for (var q in newObj) {if (p == q) {result[p] = newObj[q];}}}}return result;}/* * 弹出泡泡的默认样式 */var popMsgDefaultConfig = {containner: $(document.body), //相对定位的dom对象或对象的id.cuspStyle: "topleft",//相对定位的dom对象方位(topleft,topright,bottomleft,bottomright,leftup,leftdown,rightup,rightdown)cuspLength: 30,//尖角长度cuspWidth: 15,//尖角宽度contentWidth: 160,//消息文本框宽度contentHeight: 60,//消息文本框的高度borderWidth: 2,//边框宽度borderColor: "red",//边框颜色backColor: "#EC90F6",//背景色cuspShift: "60%",//尖角位于消息内容框上/下时，指左位移，尖角位于消息内容框左/右时，指的上位移。contentShift: "20%",//弹出框位于目标框上/下时，指左位移，弹出框位于目标框左/右时，指的上位移。textStyle: 'color: blue; font-size:small; font-family:"Microsoft YaHei";font-style:italic;'}/* * 弹出泡泡的方法 * containner: 泡泡指向的dom对象id * text: 需要显示的消息内容 * popMsgConfig： 自定义样式 * Example: popMsgShow("divUserName", "这是一个提示消息" { backColor: "gray", borderColor: "white", cuspStyle: "topleft",borderWidth: 1}); */function popMsgShow(containner, text, popMsgConfig) {popMsgClose();var config = extend(popMsgConfig, popMsgDefaultConfig);//边框样式var obj = $("#" + containner);var offset = obj.offset();var popMsg = $("<div id='divPopMsg'style='position:fixed;' ></div>");var popContent = $("<div id='divContent' style='vertical-align:middle;text-align:center; line-height: " + config.contentHeight + "px;" + " height: " + config.contentHeight + "px" + "; width: " + config.contentWidth + "px" + "; border: " + config.borderColor + " solid;border-radius: 6px;background-color: " + config.backColor + "; " + config.textStyle + "'>" + text + "</div>");var popCusp = $("<div id='divCusp' style='width: 0; height: 0; position:relative;'></div>");var popCuspInner = $("<div id='divCuspInner' style='position: absolute;'></div>");popContent.css({ borderWidth: config.borderWidth + "px", borderColor: config.borderColor, backgroundColor: config.backColor });popCusp.append(popCuspInner);popMsg.append(popContent);if (config.cuspStyle == "topleft"){var innerTop = (config.cuspLength – 3*config.borderWidth) + "px";var innerWidth = (config.cuspWidth – 2*config.borderWidth) + "px";var msgLeft = (offset.left + (config.contentShift.indexOf("px") > 0 ?
