В общем сделал как-то так.

var Mask_temp;
function Handler_Mask_Access(key,value){
	Mask_temp=value;
}
//==================================================================================================
function Handler_IP_Access(key,value){
	if(typeof value=="object"){
		var k=0;
		for (var i in value) {
			console.log(i);
			console.log(value[i]);
			k++;
			document.getElementById('id_'+key+'_'+k).value=value[i]+'/'+Mask_temp[i];		 
		}
	}else{
		//console.log("");	
	}
}
//==================================================================================================
function GetPage(link){
var test="\"IP\":\"192.168.1.4\",\"Mask\":\"255.255.255.0\",\"Mask_Access\":[11,22,33],\"IP_Access\":[\"0.0.0.0\",\"0.0.0.0\",\"0.0.0.0\",\"0.0.0.0\"],\"ComReadSNMP\":\"public\",\"ComWriteSNMP\":\"public\",\"IpTrap\":[\"192.168.1.63\",\"192.168.1.63\"],\"Comm\":[\"public\",\"public\"],\"PortTrap\":[162,288],\"TrapCheckbox\":[1,0],\"Gateway\":\"192.168.1.4\"";

		var jsonList = document.querySelectorAll('.act'); //JSON act
		var objJSON = eval('({' + test + '})');
		
		for (var Key in objJSON) {
			// console.log(Key);
