JS 为什么display设置block不能在设置none

JS 为什么display设置block不能在设置none

function select_money(select_money){
var select_money = document.getElementById(select_money);
var money = document.getElementById("money");
var money_list = document.getElementById("money_list");
var cNode =money_list.getElementsByTagName('li');

money_list.style.display="block";
for( var i=0; i<cNode.length; i++){
cNode[i].index= i;
cNode[i].onclick = function(){
money.innerHTML=this.id+"元";
money_list.style.display="none";
}
}
}

为什么运行 money_list.style.display="none"; 后
还要运行 money_list.style.display="block";

怎么让 money_list.style.display="none";运行后停止

Answer 1

onload = function() {
var money = document.getElementById("money");
var money_list = document.getElementById("money_list");
var cNode = money_list.getElementsByTagName('li');
for (var i = 0; i < cNode.length; i++) {
cNode[i].index = i;
cNode[i].onclick = function() {
money.innerHTML = this.id + "元";
money_list.style.display = "none";
}
}
}

function select_money(select_money) {
var select_money = document.getElementById(select_money);
}
