一、使用RegisterClientScriptBlock輸出js代碼塊
StringBuilder sb = new StringBuilder(); sb.Append("<input type=\"text\" id=\"txtGo\" name=\"txtGo\" style=\" width:30px\" >"); sb.Append("<input type=\"button\" id=\"btnGo\" name=\"btnGo\" value=\"跳轉\" onclick=\"pagego();\" >");
string scriptstrs = ""; scriptstrs += "function pagego(){"; scriptstrs += " var val = document.getElementById('txtGo').value;"; scriptstrs +=" if (val >"+PageCount+") {alert('不能大於'+"+PageCount+");}"; scriptstrs += "else {window.location.href = 'WordManager.aspx?page='+val;}}"; if (!Page.ClientScript.IsClientScriptBlockRegistered(this.GetType(), "keys")) { Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "keys", scriptstrs, true); }
二、使用 RegisterStartupScript輸出一次性使用的js代碼
string scriptstrs = "<script>alert('歡迎光臨!');</script>"; if (!Page.ClientScript.IsStartupScriptRegistered(this.GetType(),"welcome")) { Page.ClientScript.RegisterStartupScript(this.GetType(), "welcome", scriptstrs); }
三、使用RegisterClientScriptInclude後臺輸出已有js文件
首先創建 js文件test.js
if (!Page.ClientScript.IsClientScriptIncludeRegistered(this.GetType(), "keys"))//判斷keys是否已註冊過 { Page.ClientScript.RegisterClientScriptInclude("keys", "testjs.js"); }
四、運用Response.Write("<script>alert('ww');</script>"); 方式也可輸出簡單js代碼(不建議)
