var total = [];
for(var i = 0; i < found.length; i++){
if(total.length === 0){
total.push(found[i]);
}else{
for(var x = 0; x < total.length; x++){
if(total[x].price < found[i].price){//Here
total.splice(x, 0, found[i]);
console.log("Test");
break;
}else{
console.log("Testss");
if(x === total.length - 1){
total.push(found[i]);
}
}
}
}
}
以上代码成功运行 并且测试是console.log
for(var i = 0; i < found.length; i++){
if(total.length === 0){
total.push(found[i]);
}else{
for(var x = 0; x < total.length; x++){
if(total[x].price > found[i].price){ //The sign changed here
total.splice(x, 0, found[i]);
console.log("Test");
break;
}else{
console.log("Testss");
if(x === total.length - 1){
total.push(found[i]);
}
}
}
}
}
以上内容无效，我找不到原因，这只是一个迹象 注意：代码在其他功能中不在同一功能中 有人可以帮忙吗？

对于电子商务应用程序，我正在将产品从高价过滤到 从低到高，所以我做了这段代码这是整个代码 谁想看到任何人有答案？？注意：当我使如果 条件像第一个例子一样有效，所以问题出在 自言自语
答案 0 :(得分：0)
我阅读了您的评论
是的，它正在完美地安慰它
我确定原因是
if(x === total.length - 1){
total.push(found[i]);
}
如果遇到这种情况，此步骤将每次重复，它将无限循环，并且永远不会在if语句中运行，因为found [i]不变=>您的浏览器已停止。
