Question

我们正在将CF Server 9升级到最新的CF2018。我正面临下拉选择值和cfgrid绑定之间的绑定问题。

在cfgrid上方有一个下拉菜单，该下拉菜单最初设置为空，并列出了查询的值，而在下面的网格是将下拉选择值绑定到所获取查询的网格。

首先，由于选择了空，因此将不会获取记录，并且网格将为空。绑定URL的格式也正确。

http://127.0.0.1:8501/app/dummy.cfm?&DbFunc=getRecords&SrcID=&newSrcID=&flt_nm=&flt_iv=&flt_ct=&flt_sc=&flt_in=&pageSize=174&_cf_ajaxproxytoken=6D89B1BFAE8D17997E5A&_cf_clientid=1AFC4F973849FBAE6EAAA465492A0E0B&_cf_rc=0&_cf_nodebug=true&_cf_nocache=true&returnFormat=json&_dc=1549690631545&start=0&limit=174&page=1&sortCol=&sortDir=ASC

但是接下来，当我将下拉列表选择为新值时，URL便以这种方式形成。

http://127.0.0.1:8501/app/dummy.cfm?&&DbFunc=getRecords&SrcID=Test&SrcID=&&newSrcID=Test&&flt_nm=&&flt_iv=&&flt_ct=&&flt_sc=&&flt_in=&pageSize=174&_cf_ajaxproxytoken=6D89B1BFAE8D17997E5A&_cf_clientid=1AFC4F973849FBAE6EAAA465492A0E0B&_cf_rc=0&_cf_nodebug=true&_cf_nocache=true&returnFormat=json&_dc=1549690634739&start=0&limit=174&page=1&sortCol=&sortDir=ASC

如您所见，SrcID两次被追加，第一次为空，然后添加所选值。我在下一页将其作为逗号分隔的值接收，这是不正确的。查询参数将作为单独的参数添加，而不是取代旧的参数。

SrcID参数在顶部定义，下一个是下拉列表，直接在底部是cfgrid（在绑定中使用该参数）。预先感谢

这是下面的示例代码

<cfajaximport tags="cfform, cfinput-datefield, cftooltip, cfwindow, cfgrid, cfmessagebox">

<script type="text/javascript" language="javascript">

function doRefresh(form){
    cSrcID = form.SrcID.options[form.SrcID.selectedIndex].value;
    console.log('me'+cSrcID+'u');
    cSortFld = '';
    form.newSrcID.value = cSrcID;
}
// get client area of the browser
var cliWt = getClientWt();  // client width
var cliHt = getClientHt();  // client height

// set grid dimensions scrWidth, scrHeidht
var gWt       = 34;     // right margin
var gHt       = 180;    // top margin
var minWt     = 500;    // min width of the table
var minHt     = 280;    // min height of the table
var scrWidth  = cliWt - gWt;
var scrHeight = cliHt - gHt;
if (scrWidth < minWt) scrWidth = minWt;
if (scrHeight < minHt) scrHeight = minHt;

// set winEdit popup window dimensions
var popwinWt = 1150;
var popwinHt = 680;
var bResizePopup = 0;

if (popwinWt > cliWt) {
    bResizePopup = 1;
    popwinWt = cliWt - 10;
}
if (popwinHt > cliHt) {
    bResizePopup = 1;
    popwinHt = cliHt - 10;
}

// set winEdit2 popup window dimensions
var popwinWt2 = 900;
var popwinHt2 = 510;
var bResizePopup2 = 0;

if (popwinWt2 > cliWt) {
    bResizePopup2 = 1;
    popwinWt2 = cliWt - 10;
}
if (popwinHt2 > cliHt) {
    bResizePopup2 = 1;
    popwinHt2 = cliHt - 10;
}

// set winEdit3 popup window dimensions
var popwinWt3 = 800;
var popwinHt3 = 550;
var bResizePopup3 = 0;

if (popwinWt3 > cliWt) {
    bResizePopup3 = 1;
    popwinWt3 = cliWt - 10;
}
if (popwinHt3 > cliHt) {
    bResizePopup3 = 1;
    popwinHt3 = cliHt - 10;
}

在dummy.cfm上

根据所选的Src ID返回JSON格式的查询数据
