Dynamics Crm 365 JS实现Lookup字段的自定义过滤

条件覆盖：

1.实现方法很简单，在Form的OnLoad事件加上preFilterLookup

function preFilterLookup() {
       Xrm.Page.getControl("new_postingid").addPreSearch(function () {  // child field
           addPostingLookupFilter();
       });
  }

2.用addCustomFilter来控制

function addPostingLookupFilter() {
       var gl = Xrm.Page.getAttribute("new_special_gl_indicatorid").getValue(); // parent field
       var fetchXml = "";
      Xrm.Page.getControl("new_postingid").addCustomFilter(fetchXml); // child field
  }

全部覆盖：在onload执行

let entityName = "account";
        let viewDisplayName = "可用客户";
        let lookupControl = Xrm.Page.getControl(attributeName);  //字段名
        if (lookupControl == null) {
            return;
        }
        let id = '{2443A0FF-7988-43BC-849B-156F9B93FAD7}';
 
        let fetchXml = ""
            + "  "
            + "    "
            + "    "
            + "    "
            + "    ";
        　　 + "  "
            + "";

        let layoutXml = "";
        lookupControl.addCustomView(id, entityName, viewDisplayName, fetchXml, layoutXml, false);
        lookupControl.setDefaultView(id);
