推荐答案

大家好，



步骤如下：



步骤1：从下面的链接下载外部JavaScipt。



第2步：在eclipse中创建JSP并导入外部JS。

将外部JS导入Eclipse项目的步骤：

右键单击您的项目 - >新 - > JavaScript源文件 - >点击：高级 - >选择：链接到文件系统中的文件 - >你的Exteranl JS文件夹然后点击完成。



步骤3：复制以下两个Java脚本标签并将其粘贴到你的身体标签内。



步骤4：在onclick或onsubmit中调用check（）方法。

示例：< input type =buttonvalue =Submitonclick = check（）/>



*************************** ************************************************** ******

上面的代码将不起作用，但代码下面的代码将适用于所有情况，即使Flash插件被禁用。它会提醒您插件被禁用或启用，安装或未安装，并将您重定向到Flash网站以安装Flash播放器。



注意：我的代码需要预定义（外部）JavaScript。这适用于所有浏览器IE，Chrome，Firefox，Safari，Netscape，opera。



您可以使用以下URL并下载预定义（外部）JavaScript：

############下面的脚本是检测浏览器#############

Hi All,

Steps to follow:

Step 1: Download the External JavaScipt from below link.

Step 2: Create JSP in eclipse and import the external JS.
Steps to import external JS to Eclipse project:
Right Click on your project -> New -> JavaScript Source File -> Click :Advanced -> Select :Link to File in Filesystem -> your Exteranl JS folder and click to finish.

Step 3: Copy the below two Java scripts tags and paste it inside your body tag.

Step 4: Call the check() method in your onclick or onsubmit.
example : <input type="button" value="Submit" onclick="check()" />

***********************************************************************************
The above piece of code will not function but below code will work on all scenarios even the Flash plugin is disabled. It will alert you plugin is disabled or enabled, installed or not installed and redirect you to flash site to install the flash player.

NOTE : My code need a predefined(external) JavaScript. This will work on all the browsers IE,Chrome,Firefox,safari,Netscape,opera.

you may use the below URL and download the predefined(external) JavaScript:

############Below script is to detect the browser#############
