（一），通过Response来注册。
这种方法会把JS代码写在页面的最顶部(<html>的前面)：
Html为：
| <script>alert('test');</script> <htm> <head><title> 无标题页 </title></head> <body> <form name="form1" method="post" action="ResponseTest.aspx" id="form1"> <div> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJNzgzNDMwNTMzZGR1X58dvYJq82PoD7eO7iID3VAarQ==" /> </div> <div> </div> </form> </body> </html> |
（二）通过RegisterStartupScript注册
这种方法会把JS代码嵌入在页面的底部、表单的最后 (</form>前面)，适用于要在页面控件加载完成后运行的JS代码 ：
| <htm> <head><title> 无标题页 </title></head> <body> <form name="form1" method="post" action="ResponseTest.aspx" id="form1"> <div> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJNzgzNDMwNTMzZGR1X58dvYJq82PoD7eO7iID3VAarQ==" /> </div>
<div> </div> <script>alert('test');</script> </form> </body> </html> |
3 使用RegisterClientScriptBlock来注册
| <htm> <head><title> 无标题页 </title></head> <body> <form name="form1" method="post" action="ResponseTest.aspx" id="form1"> <div> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUJNzgzNDMwNTMzZGR1X58dvYJq82PoD7eO7iID3VAarQ==" /> </div>
<script>alert('test');</script> <div> </div> </form> </body> </html> |
4 RegisterClientScriptInclude
| <html> <head><title> 无标题页 </title></head> <body> <form name="form1" method="post" action="ResponseTest.aspx" id="form1"> <div> <input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwUKMTQ2OTkzNDMyMWRkjYxieQIBG8ed+2Q4Klx0t2vSxDQ=" /> </div>
<script src="test.js" type="text/javascript"></script> <div>
<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="/wEWAgL6tayvBgKSoqqWD3vQXcwFvwN1ZlFp+YeinBhgnZk7" /> </div> <div> <input type="submit" name="btn" value="确定" id="btn" /> </div> </form> </body> </html> |
