1: Modify the execution method of the loop
for(var i=0;i<;i++){
Execute code
}
The value that needs to be taken in this way every loop should be changed to the following
var n＝
for(var i=0;i<n;i++){
Execute code
}
2: Number of times to modify the dom operation
dom batch insertion of similar nodes is worse than constructing an object first and inserting it once.
For example, the following method is reasonable:
var div=("div");
for(var i=0;i<10;i++)[
var element=("a");
="";
(element);
}
//Insert once after building the object
(div);
3: Reducing the reference level of objects can reduce the complexity of browser resolution of objects
For example, one method is (params)
Don't use it like this every time, you
var loadXml=;
loadXml(params);
for(var i=0;i<;i++){
Execute code
}
