我试图冻结一个按钮时,点击,这样用户就不会双击意外造成重复实体。这是我的密码:

      private void FreezeButton()
    {
        var sb = new StringBuilder();
        sb.Append("if (typeof(Page_ClientValidate) == 'function') { ");

        sb.Append("var oldPage_IsValid = Page_IsValid; var oldPage_BlockSubmit = Page_BlockSubmit;");
        sb.Append("if (Page_ClientValidate('" + btnAdd.ValidationGroup + "') == false) {");
        sb.Append(" Page_IsValid = oldPage_IsValid; Page_BlockSubmit = oldPage_BlockSubmit; return false; }} ");

        sb.Append("this.value = 'Processing...';");
        sb.Append("this.disabled = true;");

        sb.Append(Page.ClientScript(btnAdd, null) + ";");
        sb.Append("return true;");

        string submitButton = sb.ToString();

        btnAdd.Attributes.Add("onclick", submitButton);
    }

首先,我尝试在没有 页面.ClientScript 它给了我一个错误:名字 'ClientScript' 在当前上下文中不存在

然后我看着 This

Page.ClientScript 是一个属性,不能像方法一样使用它。可能你在找 Page.ClientScript.RegisterClientScriptBlock()

假设你在处理 btnAdd FreezeButton 方法事件处理时,应该替换要包含的内容 RegisterClientScriptBlock

protected void FreezeButton(object sender, EventArgs e)
{
    var sb = new StringBuilder();
    sb.Append("function validate() { ")

    // script content here, skipped for brevity

    sb.Append("}");

    // use RegisterClientScriptBlock to attach script content into <script> tag inside page body
    Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Example", sb.ToString(), true);

    // handle client-side event click if the button is a server control
    btnAdd.OnClientClick = "validate()";
}

然后,处理的服务器端click事件这样地:

<asp:Button ID="btnAdd" runat="server" OnClick="FreezeButton" ... />

我找到了解决办法:

  private void FreezeButton()
    {
        var sb = new StringBuilder();
        sb.Append("if (typeof(Page_ClientValidate) == 'function') { ");

        sb.Append("var oldPage_IsValid = Page_IsValid; var oldPage_BlockSubmit = Page_BlockSubmit;");
        sb.Append("if (Page_ClientValidate('" + btnAdd.ValidationGroup + "') == false) {");
        sb.Append(" Page_IsValid = oldPage_IsValid; Page_BlockSubmit = oldPage_BlockSubmit; return false; }} ");

        sb.Append("this.value = 'Processing...';");
        sb.Append("this.disabled = true;");

        sb.Append(Page.ClientScript.GetPostBackEventReference(btnAdd, null) + ";");
        sb.Append("return true;");

        string submitButtonOnclickJs = sb.ToString();

        btnAddReceipt.Attributes.Add("onclick", submitButtonOnclickJs);
    }
