In js numeric calculation, parseInt is used for data type conversion (jquery) and parseintjquery

The data obtained by js is of the string type by default. If you perform a numerical operation, you must use parseInt to convert the data to a numerical value.

Html code:

Copy codeThe Code is as follows:
<Div id = "archive">
<Input type = "hidden" name = "page" value = "1"/>
</Div>

Js Code:

Copy codeThe Code is as follows:
$ ("# Archive"). bind ('click', function (){

Var page = $ ("input [name = 'page']"). val ();
// Use parseInt to calculate the value
$ ("Input [name = 'page']"). val (parseInt (page) + 1 );

});

In jquery, how do I convert a string-type number to an integer (number) type?

Var x = parseInt ($ ("# text1"). val ());

Question about Jquery type conversion?

It is best not to use the JS method, all kinds of risks, it is best to convert the number type to multiply by 1
Var data = param. substring (param. length-2, param. length) * 1 + 6;
