使用jQuery遍历所有DOM元素

Posted 2021-02-25

This code will walk all elements from a given selector.

function doStuff(child, type) {
    if(typeof type !== 'undefined' && type != ""){
        /** HERE **/
    }
}
 
function walk(children){
    if (typeof children == "undefined" || children.size() === 0) {
        return;
    }
 
    children.each(function(){
        var child = $(this);
        if (child.children().size() > 0) {
            walk(child.children());
        }
        doStuff(child, this.type);
    });
}
 
walk($("#ka-registration-vital-information-form .participant"));
