createElement is the concept of using the W3C DOM object model to create child nodes, that is, child elements in HTML
Copy the codeThe code is as follows:
<script>
= function () {
var input = ('input');
var button = ('input');
='text';
= 'text';
='1';
='button';
='Add to add';
= '40px';
= '23px';
(input);
(button);
= function(){
var value = ;
= value * 1 + 1;
}
}
</script>
Note: value is actually a character. If you change =value*1+1; to =value+1; the result will appear 111111. It constantly adds 1 in the form of a character, so at this time the value*1 can convert the value value into Int type.
Summarize:
To ultimately solve the compatibility problem of the createElement method, you should still pay attention to judging the browser. For IE, you can use its unique method by passing in a legitimate HTML code string as a parameter for createElement. Non-IE browsers still use the standard method of W3C specification.
