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" onclick="return confirm('Yes/No'););

<!-----------按钮提示框---------->

<input type="button" name="btn2" id="btn2" value="提示" onclick="javaScript:alert('您确定要删除吗？');

<!-----------提交按钮---------->

<input type="button" value="提交" onclick="javaScript:window.location.href='http://www.baidu.com';"/>

<!-----------关闭按钮---------->

<input type="button" value="关闭" onclick="javaScript:window.close();">

<!-----------返回并关闭连接---------->

<a href="#" onclick="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" onclick="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" onclick="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

-->
