Page_ClientValidate() 与多个 ValidationGroups - 如何同时显示多个摘要? [英] Page_ClientValidate() with multiple ValidationGroups - how to show multiple summaries simultaneously?

问题描述

ASP.NET 2.0.假设我有两个验证组 valGrpOne 和 valGrpTwo；和两个验证摘要 valSummOne 和 valSummTwo；拆分部分的原因纯粹是审美.一个提交按钮，触发两个组的验证.

ASP.NET 2.0. Lets say i have two Validation Groups valGrpOne and valGrpTwo; and two Validation Summaries valSummOne and valSummTwo; Reason for breaking up sections is purely aesthetic. One submit button which triggers validation on both groups.

现在我想触发客户端验证，并希望同时显示两个验证摘要；

Now i want to trigger Client-Side validation, AND want BOTH validation summaries to display at the same time;

所以我设置了一个在 btnSubmit 上调用的 Javascript 函数，在这个函数中我连续调用 Page_ClientValidate("valGrpOne") 和 Page_ClientValidate("valGrpTwo");问题是一次只显示一个摘要(但我真的想同时显示！)

So i setup a Javascript function which gets called upon btnSubmit, and inside this function i call Page_ClientValidate("valGrpOne") and Page_ClientValidate("valGrpTwo") in succession; Problem is only one summary shows at a time (But i really want both to show!)

关于如何从客户端代码同时显示两个验证摘要的任何想法?

Any ideas on how to get both validation summaries to display simultaneously, from client-side code?

与以下问题非常相似，该问题为服务器端提供答案.一个按钮触发多个验证组?

Very similar to the following question, which answers for server-side. Triggering multiple validation groups with a single button?

推荐答案

好的，所以答案并不简单.客户端验证的默认行为似乎是仅显示刚刚验证的最新组/摘要.但是一些 Javascript tweeking 给了我一个可以接受的答案.

Ok, so the answer was not simple. It seems the default behaviour of client-side validation is to show only the lastest group / summary that has just been validated. But a bit of Javascript tweeking gave me an acceptable answer.

随时提出改进意见.

   <script type="text/javascript" language="javascript">
    /* Manual client-side validation of Validator Groups */
    function fnJSOnFormSubmit() {
        var isGrpOneValid = Page_ClientValidate("valGrpOne");
        var isGrpTwoValid = Page_ClientValidate("valGrpTwo");

        var i;
        for (i = 0; i < Page_Validators.length; i++) { 
            ValidatorValidate(Page_Validators[i]); //this forces validation in all groups
        }

        //display all summaries.
        for (i = 0; i < Page_ValidationSummaries.length; i++) {
            summary = Page_ValidationSummaries[i];
            //does this summary need to be displayed?
            if (fnJSDisplaySummary(summary.validationGroup)) {
                summary.style.display = ""; //"none"; "inline";
            }
        }

        if (isGrpOneValid && isGrpTwoValid)
            return true; //postback only when BOTH validations pass.
        else
            return false;
    }


    /* determines if a Validation Summary for a given group needs to display */
    function fnJSDisplaySummary(valGrp) {
        var rtnVal = false; 
        for (i = 0; i < Page_Validators.length; i++) {
            if (Page_Validators[i].validationGroup == valGrp) { 
                if (!Page_Validators[i].isvalid) { //at least one is not valid.
                    rtnVal = true;
                    break; //exit for-loop, we are done.
                }
            }
        }
        return rtnVal;
    }
</script>
