从asmx调用javascript函数

本文关键字：函数 javascript 调用 asmx | 更新日期: 2023-09-27 18:25:16

我想从asmx返回javascript函数，如下所示。。

所有html标记都返回，但checkNewMsg变体'script-tag'不返回！到底发生了什么？

请告知

 <script type="text/javascript">
    function getWindow(FromUserID, UserID, PerID, UserName) {
        $.ajax({
            type: "POST",
            url: "TestMessageService.asmx/OpenWindow",
            data: "{'FromUserID': '" + FromUserID + "', 'ClickedUserID': '" + UserID + "', 'ClickedPerID': '" + PerID + "', 'ClickedUserName': '" + UserName + "'}",
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function (response) {
                var msgs = response.d;
                $('#div_Panel').append(msgs).fadeIn("slow");
                var elements = $('.panelContent');
                for (var i = 0; i < elements.length; i++) {
                    elements[i].scrollTop = elements[i].scrollHeight;
                }
            },
            failure: function (msg) {
                $('#div_Panel').text(msg);
            }
        });
    }
</script>
[WebMethod]
[System.Web.Script.Services.ScriptMethod(ResponseFormat = System.Web.Script.Services.ResponseFormat.Json)]
public string OpenWindow(string FromUserID, string ClickedUserID, string ClickedPerID, string ClickedUserName)
{ 
    string checkNewMsg = "<script type='"text/javascript'">window.setInterval(fc_" + ClickedUserName.Replace(" ", "") + ", 10000); function fc_" + ClickedUserName.Replace(" ", "") + "() { alert('" + ClickedUserName + "'); }</script>";
    StringBuilder sb = new StringBuilder();
    sb.Append(checkNewMsg + "<div class='"ch_Box'">");
    sb.Append("<div class='"ch_Header'">");
    sb.Append("<div style='"float:left;margin-top: 9px;margin-left: 8px;'"><img src='"Images/Status.png'"></div>");
    sb.Append("<div id='"roomUsers'" class='"ch_HeaderItem'">" + ClickedUserName + "</div>");
    sb.Append("<div onclick='"closePanel(this)'" style='"width: 23px; height: 27px; cursor: pointer; position: absolute; margin-left: 232px;'"><img style='"height: 20px; margin-top: 4px;'" src='"Images/close.png'"></div>");
    sb.Append("<div id='"cont_" + ClickedUserID + "'" class='"panelContent'">" + FillMessages(roomID, FromUserID.ToInt()) + "</div>");
    sb.Append("<div class='"ch_Text'">");
    sb.Append("<input id='"msg_" + FromUserID + "_" + ClickedUserID + "_" + ClickedPerID + "_" + roomID + "'" type='"text'" class='"inp'" onkeypress='"PushText(this)'" autocomplete='"off'" /></div>");
    sb.Append("</div></div>");
    return sb.ToString();
}

从asmx调用javascript函数

我不知道为什么不返回script标记一个asmx，但当我删除该标记，然后在js端添加script标记后再返回值时，问题就解决了。

就像这样；

在asmx侧；

string checkNewMsg = "window.setInterval(fc_" + ClickedUserName.Replace(" ", "") + ", 10000); function fc_" + ClickedUserName.Replace(" ", "") + "() { alert('" + ClickedUserName + "'); }#func#";

在Js侧；

 success: function (response) {
                var msgs = response.d;
                var arrCont = msgs.split('#func#');
                var MsgCont = "<script type='"text/javascript'">" + arrCont[0] + "<'/script>";
