Using LOOP in fetchxml

Question

Hi, I deeply need your help. I've try to use an array in a condition part, but it doesn't work. Here is my code:
var fetchXml = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='true'>" +
"<entity name='new_pledge'>" +
"<attribute name='new_name' />" +
"<attribute name='new_pledgeid' />" +
"<attribute name='new_marketvalue' />" +
"<order attribute='new_name' descending='false' />" +
"<filter type='or'>" +
"<condition attribute='new_pledgeid' operator='eq' value='"
for (var i = 0; i < gravid.length; i++) {
+ gravid[i] + "' />" ;
+
"</filter>" +
"</entity>" +
"</fetch>";
var layoutXml = "<grid name='resultset' object='1' jump='name' select='1' icon='1' preview='1'>" +
"<row name='result' id='new_pledgeid'>" +
"<cell name='new_name' width='300' />" +

Try below code
var fetchXml = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='true'>" +
"<entity name='new_pledge'>" +
"<attribute name='new_name' />" +
"<attribute name='new_pledgeid' />" +
"<attribute name='new_marketvalue' />" +
"<order attribute='new_name' descending='false' />" +
"<filter type='or'>" +
"<condition attribute='new_pledgeid' operator='in' >";
for (var i = 0; i < gravid.length; i++)
fetchXml += "<value>{" + gravid[i] + "}</value>";// if you having {} with guid in gravid, then please remove the hardcoded "{}" from for loop
fetchXml += " </condition>" +
"</filter>" +
"</entity>" +
"</fetch>";
