This time I will bring you the method to solve the incompatibility of easyui in ie. What are the precautions to solve the incompatibility of easyui in ie. The following is a practical case, let's take a look.

A few days ago, the project entered the final stage of preparation for launch. During the test, it was suddenly discovered that the time obtained using easyui's datetimebox plug-in could not be obtained later than the current time in IE. This was written at the time:

	$(selector).datetimebox(
	{
formatter : function(date) {
	var y = date.getFullYear();
	var m = date.getMonth() + 1;
	var d = date.getDate();
	var h = date.getHours(); //获取当前小时数(0-23)
	var mi = date.getMinutes(); //获取当前分钟数(0-59)
	var s = date.getSeconds(); 
	var result = y + '-' + (m < 10 ? '0' + m : m) + '-' + (d < 10 ? '0' + d : d)
+ " " + (h < 10 ? '0' + h : h)
+ ":" + (mi < 10 ? '0' + mi : mi);	
	//console.log(result+"--第127行");
	if(second==false){
	} else {
result += ":" + (s < 10 ? '0' + s : s);
	}
	return result;
},
  parser : function(s) {
	var t = Date.parse(s);
	if (!isNaN(t)) {
return new Date(t);
	} else {
return new Date();
	}
}
	});

There is no problem when testing mainstream browsers such as Google Chrome. The time at the beginning of the echo can be displayed and the time can be selected. However, when I went to IE, I found that I could not select the time and the echo was displayed. The date is also wrong, it is always the current time. After debugging for a long time, I discovered that

ie browser does not support the parse() method of js. The parse() method parses the date and converts it into milliseconds of the date.

formatter is the format for formatting dates. Parser parses your formatted date. For the specific writing method, please see the API diagram I captured:

Because parse cannot be used in IE~ As a result, the formatted date time cannot be parsed and displayed under IE. The following is the code I modified myself:

$(selector).datetimebox( 
  { 
  formatter : function(date) { 
   var y = date.getFullYear(); 
 var m = date.getMonth()+1; 
 var d = date.getDate(); 
 var h = date.getHours(); 
 var min = date.getMinutes(); 
 return y+'-'+(m<10?('0'+m):m)+'-'+(d<10?('0'+d):d)+' '+(h<10?('0'+h):h)+':'+min; 
  }, 
  parser : function(s) { 
 var ss = (s.split(" ")); 
 var ymd = ss[0].split("-"); 
 var hms = ss[1].split(":"); 
 //console.log(ymd+" "+hms); 
 var y = parseInt(ymd[0],10); 
 var m = parseInt(ymd[1],10); 
 var d = parseInt(ymd[2],10); 
 var h = parseInt(hms[0],10); 
 var min = parseInt(hms[1],10); 
 if (!isNaN(y) && !isNaN(m) && !isNaN(d) && !isNaN(h) && !isNaN(min)){ 
 return new Date(y,m-1,d,h,min); 
 } else { 
 return new Date(); 
 } 
  } 
  });

formatterThe formatted date is xxxx-xx-xx xx:x. Therefore, when parsing below, the date and time are first separated by the space between them. ss[0]==xxxx-xx-xx, ss[1]==xx:xx. In this case, divide them into numbers through - and:. In this case, the correct date format can be returned by directly writing it into the parameters of new Date()~~ Well, after testing, it is perfectly compatible with this cheating IE. browser.

I suddenly discovered a bug in this method when using it today, that is, if there is no data in the datetime time frame at the beginning, a split error will be reported, so I modified it today and added an empty judgment:

if(s==""){ 
 return new Date(); 
 }else{ 
 //alert(s); 
 var ss = (s.split(" ")); 
 var ymd = ss[0].split("-"); 
 var hms = ss[1].split(":"); 
 //console.log(ymd+" "+hms); 
 var y = parseInt(ymd[0],10); 
 var m = parseInt(ymd[1],10); 
 var d = parseInt(ymd[2],10); 
 var h = parseInt(hms[0],10); 
 var min = parseInt(hms[1],10); 
 if (!isNaN(y) && !isNaN(m) && !isNaN(d) && !isNaN(h) && !isNaN(min)){ 
  return new Date(y,m-1,d,h,min); 
 } else { 
  return new Date(); 
 } 
 }

It should be noted here that s is a

stringtype~so you cannot use s==null to make a judgment condition~

I believe you have mastered the method after reading the case in this article. For more exciting content, please pay attention to other related articles on the php Chinese website!
