js基础功能

一、js的三种最常见的对话框 //====================== JS最常用三种弹出对话框 ========================     //弹出对话框并输出一段提示信息     function ale() {         //弹出一个对话框         alert("提示信息！");     }     //弹出一个询问框，有确定和取消按钮     function firm() {         //利用对话框返回的值 （true 或者 false）         if (confirm("你确定提交吗？")) {             alert("点击了确定");         }         else {             alert("点击了取消");         }     }     //弹出一个输入框，输入一段文字，可以提交     function prom() {         var name = prompt("请输入您的名字", ""); //将输入的内容赋给变量 name ，         //这里需要注意的是，prompt有两个参数，前面是提示的话，后面是当对话框出来后，在对话框里的默认值         if (name)//如果返回的有内容         {             alert("欢迎您：" + name)         }     } 二、点击按钮时常用的6中提示框和操作 <!-----------按钮提示框----------> <input type="button" name="btn2" id="btn2" value="删除" οnclick="return confirm('Yes/No');); <!-----------按钮提示框----------> <input type="button" name="btn2" id="btn2" value="提示" οnclick="javaScript:alert('您确定要删除吗？'); <!-----------提交按钮----------> <input type="button" value="提交" οnclick="javaScript:window.location.href='http://www.baidu.com';"/> <!-----------关闭按钮----------> <input type="button" value="关闭" οnclick="javaScript:window.close();"> <!-----------返回并关闭连接----------> <a href="#" οnclick="javascript:;window.opener.location.reload();window.close()">返回</a> javaScript:window.location.reload();//返回当前页并刷新 <!-----------返回上一级页面----------> <input type="button" name="button" value="< 返回" οnclick="javascript:history.go(-1)"/> 三、弹出独立窗口 //关闭,父窗口弹出对话框,子窗口直接关闭 this.Response.Write("<script language=javascript>window.close();</script>"); //关闭,父窗口和子窗口都不弹出对话框,直接关闭 this.Response.Write("<script>"); this.Response.Write("{top.opener =null;top.close();}"); this.Response.Write("</script>"); //弹出窗口刷新当前页面width=200 height=200菜单。菜单栏,工具条,地址栏,状态栏全没有 this.Response.Write("<script language=javascript>window.open('rows.aspx','newwindow','width=200,height=200')</script>"); //弹出窗口刷新当前页面 this.Response.Write("<script language=javascript>window.open('rows.aspx')</script>"); this.Response.Write("<script>window.open('WebForm2.aspx','_blank');</script>"); //弹出提示窗口跳到webform2.aspx页(在一个IE窗口中) this.Response.Write(" <script language=javascript>alert('注册成功');window.window.location.href='WebForm2.aspx';</script> "); //关闭当前子窗口,刷新父窗口 this.Response.Write("<script>window.opener.location.href=window.opener.location.href;window.close();</script>"); this.Response.Write("<script>window.opener.location.replace(window.opener.document.referrer);window.close();</script>"); //子窗口刷新父窗口 this.Response.Write("<script>window.opener.location.href=window.opener.location.href;</script>"); this.Response.Write("<script>window.opener.location.href='WebForm1.aspx';</script>"); //弹出提示窗口.确定后弹出子窗口(WebForm2.aspx) this.Response.Write("<script language='javascript'>alert('发表成功！');window.open('WebForm2.aspx')</script>"); //弹出提示窗口,确定后,刷新父窗口 this.Response.Write("<script>alert('发表成功！');window.opener.location.href=window.opener.location.href;</script>"); //弹出相同的一页 <INPUT type="button" value="Button" οnclick="javascript:window.open(window.location.href)"> // Response.Write("parent.mainFrameBottom.location.href='yourwebform.aspx?temp=" +str+"';"); <SCRIPT LANGUAGE="javascript"> <!-- window.open ('page.html', 'newwindow', 'height=100, width=400, top=0, left=0, toolbar=no, menubar=no, scrollbars=no, resizable=no,location=n o, status=no') //这句要写成一行 --> Javascript中的e.keyCode大全
