//Display page number
function xsym(ymsy) {
//Page number ymym
ymym = ymsy 1;
//Move out other pages selected
$( '#sp1>span').removeClass('selected');
//Initial current page number ymsy 1
$('#sp1>span.i' ymym '').addClass("selected") ;
}
The problem encountered is that when $('#Button1') is clicked for the first time, the code logic is normal and the page can be turned normally. When $('#Button1') is clicked again, ymsy The value cannot be reset to 0. Clicking the next page will trigger the next page event twice. Please ask a jQuery expert for an answer! ! !

When binding an event repeatedly, you should determine whether the event has already been bound. You can use global variables to determine.

Quoting the reply from datiexiong on the 1st floor: If you bind an event repeatedly, you should judge whether the event has been bound. You can use global variables to judge. .

var button1Click = false;

$('#Button1').click(function(){
if(!buttonClick)

{

buttonClick=true;
//Code of the original bound event
}
});

This can solve the confusion caused by multiple clicks on $('#Button1'). How to change it if you want to click on $('.btn')? Just click on a type of button? Let him execute it.

Can give btn adds attributes, using setAttribute("clicked",true),
When getAttribute("clicked") is false or undefined, it is considered that it has not been bound, otherwise the task has been bound.

Thank you very much, I will go to the next page , the next page, the first page, and the last page were solved after adding $(element).unbind('click');$(element).bind('click'); respectively. ThankYou.
