3. Practice of crm2011 programming-Implementation of association between option sets (drop-down boxes)

Requirements:Based on the selection of different "Reflection categories", Shuai selects different "Reflection content ".

Field description:Reflected category: hxcs_feedbacktype; reflected content: hxcs_feedbacktype

Solution:To set the association between two option sets, we can perform some special processing when setting values for the two option sets. For example, if the value of a category is 00001, 100100001, the corresponding content can be set to category value +, that is, and so on. For example:

The JS Code is as follows:

function onFeedBackTypeChange() {    var _feedbackcontent = Xrm.Page.getControl("hxcs_feedbackcontent").getAttribute().getOptions();    var backType = Xrm.Page.getControl("hxcs_feedbacktype").getAttribute().getValue();    Xrm.Page.getControl("hxcs_feedbackcontent").clearOptions();    if (backType == null)        return;    backType = backType.toString();    var iLen = _feedbackcontent.length;    var iPos = 0;    for (var i = 0; i < iLen; i++) {        if (_feedbackcontent[i].value.substr(0, backType.length) == backType) {            Xrm.Page.getControl("hxcs_feedbackcontent").addOption(_feedbackcontent[i], iPos);            iPos++;        }    }    Xrm.Page.getControl("hxcs_feedbackcontent").getAttribute().setValue(null);}
