通过 Json 将 javascript 数组传递给 Coldfusion CFC

发布于 2024-12-23 04:04:03 字数 1759 浏览 2 评论 0原文

我使用此 javascript 捕获在 Flexigrid 中选中的所有复选框,并尝试将此行 id 数组发送到 CFC

function removeCertidao(){
    var allVals = [];
    $("input[id='certidao']:checked").each(function() {
        allVals.push($(this).val());
    });
    if (allVals.length == 0) {
        alert('É necessário escolher ao menos uma certidão.');
        return false;
    } else {
        alert(allVals);
    }
    $.ajax({
        type: "post",
        url: "../../CFC/CRC.cfc",
        data: {
            method: "removeCertidaoCRC",
            numSeqCertidao: allVals,
        },
        dataType: "json",
        success: function(){
            alert('YES');
        },
        error: function(){
            alert('NO');
        }
    });             
 }

CFC 下面

<cffunction access="remote" name="removeCertidaoCRC" returntype="boolean">
    <cfargument name="numSeqCertidao" type="array" required="true">
<cftry>
    <cftransaction>
        <cfquery datasource="portalCompras">
        UPDATE CRC_CERTIDAO CC
           SET CC.ncdcrcstatus = 0
             WHERE CC.NCDCRCCERTIDAO in <cfqueryparam value="#numSeqCertidao#"
                                                          cfsqltype="cf_sql_integer"
                                                          list="yes">
    </cfquery>
        </cftransaction>
    <cftransaction action="commit" />
    <cfreturn 0>
    <cfcatch type="any">
        <cftransaction action="rollback" />
        <cfreturn #cfcatch.message#>
        </cfcatch>
</cftry>
</cffunction>

,当我尝试运行此函数时,我的服务器回答传递给 removeCertidaoCRC 函数的 NUMSEQCERTIDAO 参数不是类型大批。

我最近刚刚进入的一个延迟项目已经没有选择了。

i use this javascript to capture all checkboxes checked in a flexigrid and try to send this array of row ids to an CFC

function removeCertidao(){
    var allVals = [];
    $("input[id='certidao']:checked").each(function() {
        allVals.push($(this).val());
    });
    if (allVals.length == 0) {
        alert('É necessário escolher ao menos uma certidão.');
        return false;
    } else {
        alert(allVals);
    }
    $.ajax({
        type: "post",
        url: "../../CFC/CRC.cfc",
        data: {
            method: "removeCertidaoCRC",
            numSeqCertidao: allVals,
        },
        dataType: "json",
        success: function(){
            alert('YES');
        },
        error: function(){
            alert('NO');
        }
    });             
 }

CFC Below

<cffunction access="remote" name="removeCertidaoCRC" returntype="boolean">
    <cfargument name="numSeqCertidao" type="array" required="true">
<cftry>
    <cftransaction>
        <cfquery datasource="portalCompras">
        UPDATE CRC_CERTIDAO CC
           SET CC.ncdcrcstatus = 0
             WHERE CC.NCDCRCCERTIDAO in <cfqueryparam value="#numSeqCertidao#"
                                                          cfsqltype="cf_sql_integer"
                                                          list="yes">
    </cfquery>
        </cftransaction>
    <cftransaction action="commit" />
    <cfreturn 0>
    <cfcatch type="any">
        <cftransaction action="rollback" />
        <cfreturn #cfcatch.message#>
        </cfcatch>
</cftry>
</cffunction>

when i try to run this function, my server answers that The NUMSEQCERTIDAO argument passed to the removeCertidaoCRC function is not of type array.

I'm running out of options on a delayed project in which i entered just recently.

jQuery 会很好地发送分开的数组,如 numSeqCertidao[] = 'val1', numSeqCertidao[] = 'val2' ... 但 ColdFusion 处理得很糟糕,并且不会接受它并重建它作为一个数组。

您的 JavaScript 未发送 JSON 格式的数据,dataType 选项用于响应数据的格式。根据您的需求,我建议您将 numSeqCertidao 作为列表发送,为 CFC 方法的参数提供一种字符串类型,并保留其余部分不变,应该可以正常工作。

稍微修改一下代码:

function removeCertidao(){
    var allVals = [];
    $("input[id='certidao']:checked").each(function() {
        allVals.push($(this).val());
    });
    if (allVals.length == 0) {
        alert('É necessário escolher ao menos uma certidão.');
        return false;
    } else {
        alert(allVals);
    }
    $.ajax({
        type: "post",
        url: "../../CFC/CRC.cfc",
        data: {
            method: "removeCertidaoCRC",
            numSeqCertidao: allVals.join(),
        },
        dataType: "json",
        success: function(){
            alert('YES');
        },
        error: function(){
            alert('NO');
        }
    });             
 }

<cffunction access="remote" name="removeCertidaoCRC" returntype="boolean">
    <cfargument name="numSeqCertidao" type="string" required="true">
<cftry>
    <cftransaction>
        <cfquery datasource="portalCompras">
        UPDATE CRC_CERTIDAO CC
           SET CC.ncdcrcstatus = 0
             WHERE CC.NCDCRCCERTIDAO in <cfqueryparam value="#numSeqCertidao#"
                                                          cfsqltype="cf_sql_integer"
                                                          list="yes">
    </cfquery>
        </cftransaction>
    <cftransaction action="commit" />
    <cfreturn 0>
    <cfcatch type="any">
        <cftransaction action="rollback" />
        <cfreturn #cfcatch.message#>
        </cfcatch>
</cftry>
</cffunction>

jQuery will do a good job of sending the array separated like numSeqCertidao[] = 'val1', numSeqCertidao[] = 'val2' ... but ColdFusion handles this badly and does not take this and rebuild it as an array.

Your JavaScript is not sending data in JSON format, the dataType option is for the format of the response data. For your needs I would suggest you send numSeqCertidao as a list, give your CFC method's argument a type of string and leave the rest of it as is, should work fine.

Slightly amended code:

function removeCertidao(){
    var allVals = [];
    $("input[id='certidao']:checked").each(function() {
        allVals.push($(this).val());
    });
    if (allVals.length == 0) {
        alert('É necessário escolher ao menos uma certidão.');
        return false;
    } else {
        alert(allVals);
    }
    $.ajax({
        type: "post",
        url: "../../CFC/CRC.cfc",
        data: {
            method: "removeCertidaoCRC",
            numSeqCertidao: allVals.join(),
        },
        dataType: "json",
        success: function(){
            alert('YES');
        },
        error: function(){
            alert('NO');
        }
    });             
 }

<cffunction access="remote" name="removeCertidaoCRC" returntype="boolean">
    <cfargument name="numSeqCertidao" type="string" required="true">
<cftry>
    <cftransaction>
        <cfquery datasource="portalCompras">
        UPDATE CRC_CERTIDAO CC
           SET CC.ncdcrcstatus = 0
             WHERE CC.NCDCRCCERTIDAO in <cfqueryparam value="#numSeqCertidao#"
                                                          cfsqltype="cf_sql_integer"
                                                          list="yes">
    </cfquery>
        </cftransaction>
    <cftransaction action="commit" />
    <cfreturn 0>
    <cfcatch type="any">
        <cftransaction action="rollback" />
        <cfreturn #cfcatch.message#>
        </cfcatch>
</cftry>
</cffunction>

您传递给 CFC 的是一个 Javascript 数组。它不是 ColdFusion 阵列。所以对于 CFC 来说它看起来像一个字符串。将类型更改为“字符串”或“任意”,或者完全省略它。

What you're passing to the CFC is a Javascript array. It's not a ColdFusion array. So to the CFC it looks like a string. Change type to "string", or "any", or just omit it completely.
