注册启动脚本 [英] Register Startup Script

问题描述

我想验证当前案例是否无法重新分配给系统上的另一个用户，并发送一条通知消息，指示您无法执行此操作.

我的第一个想法是注册一个启动脚本，该脚本将发送警报消息，但是由于某种原因，我无法使其正常工作.

我已经在下面发布了我的代码.也许有人可以指导我找到可行的解决方案.

I want to validate that a current case cannot be reassigned to another user on the system, and send a notification message indicating that you can''t do that.

My first thought is to register a startup script, that will send the alert message, but for some reason, I am not able to get it to work.

I have posted my code below. Perhaps some one can guide me towards a workable solution.

ScriptManager.RegisterStartupScript(this, this.GetType(), "myAlert", "javascript:alert(''Since you are already working on " + Functions.ToString(caseCount) + " cases, you cannot assign any new case to yourself.'');", true);

推荐答案

使用该对象之前必须先声明一个脚本管理器对象.

You have to declare a script manager object first before using it.

ClientScriptManager cs = this.Page.ClientScript
Type rsType = this.GetType()

if (!cs.IsClientScriptInludeRegistered(rsType, "jQuery")) {
     cs.RegisterStartupScript("jQuery", "~/script/jquery.js"))
}

就您的JavaScript而言，它看起来像是一条警告消息，指示验证失败.在这种情况下，最佳实践是在按钮对象列表中使用onClientClick，而不注册启动脚本.

As far as your javascript goes, it looks like a alert message that indicates validation has failed. In that case, best practice is to use onClientClick, in the buttons object list, and not register a startup script.

btSubmit.onClientClick = "alert("validation failed"); return false;"
