AngularJs输出字符串换行\n或不管用时，要用ng-bind-html配合解决

1、controller

/*显示条件表达式*/
var myConExpController=['$scope', '$http','myCache', function($scope, $http,myCache) {
	//显示当前条件表达式
	$scope.$on('showConExpEvent',function(event,data){
			var len=data.length;
			var dataStr="";
			if(len<=80){
				//
				dataStr=data;
			}else{
				//超长字符串需截断字符显示
				var s=Math.ceil(len/80);
				var i=0;
				var start=0;
				var end=0;
				do{
					start=i*80;
					end=(++i)*80;
					if(end>len){
						end=len;
					}
					dataStr+=trimStr(data.substring(start,end)+"<br/>");
					--s;
				}while(s>0);
			}
			$scope.conExpModel=trimStr(dataStr);
	});
}];

2、html

<td colspan="6" ng-controller="myConExpController" style="width: 550px;">
							{{'PROPERTY.SEQUENCEFLOW.CONDITION.STATIC' | translate}}<br>
							<span ng-model="conExpModel" style="color: #444444;font-size: 14px;background-color: #f0f0f0;width: 550px;overflow: hidden;" ng-bind-html="conExpModel"></span>
						</td>
