在js代码中引入以下代码，让高版本的jquery兼容toggle事件。代码如下：
PHP;">
/**
* Replacement for toggle
*/
jQuery.fn.toggle = function( fn,fn2 ) {
// Don't mess with animation or css toggles
if ( !jQuery.isFunction( fn ) || !jQuery.isFunction( fn2 ) ) {
return oldToggle.apply( this,arguments );
}
// Save reference to arguments for access in closure
var args = arguments,guid = fn.guid || jQuery.guid++,i = 0,toggler = function( event ) {
// Figure out which function to execute
var lastToggle = ( jQuery._data( this,"lastToggle" + fn.guid ) || 0 ) % i;
jQuery._data( this,"lastToggle" + fn.guid,lastToggle + 1 );
// Make sure that clicks stop
event.preventDefault();
// and execute the function
return args[ lastToggle ].apply( this,arguments ) || false;
};
// link all the functions,so any of them can unbind this click handler
toggler.guid = guid;
while ( i < args.length ) {
args[ i++ ].guid = guid;
}
return this.click( toggler );
};
