Javascript 如何使用html5本地存储加载值
我想把我的输入也作为表格中的输出。我复制了下面的代码,因为我只想知道如何获得输出 我想我必须改变这个Javascript 如何使用html5本地存储加载值,javascript,html,input,Javascript,Html,Input,我想把我的输入也作为表格中的输出。我复制了下面的代码,因为我只想知道如何获得输出 我想我必须改变这个 <input type="button" value="load" onclick="load_local();"/ 试验 函数save() { var arr=新数组(); var obj1=parseInt(document.getElementById(“txt1”).value); var obj2=parseInt(document.getElementByI

函数save()
{
var arr=新数组();
var obj1=parseInt(document.getElementById(“txt1”).value);
var obj2=parseInt(document.getElementById(“txt2”).value);
var obj3=parseInt(document.getElementById(“txt3”).value);
var obj4=parseInt(document.getElementById(“txt4”).value);
var obj5=parseInt(document.getElementById(“txt5”).value);
var obj6=parseInt(document.getElementById(“txt6”).value);

arr.push(obj1);
arr.push(obj2);
arr.push(obj3);
arr.push(obj4);
arr.push(obj5);
arr.push(obj6);
arr.push(obj7);
arr.push(obj8);
var arrodered=u.sortBy(arr,函数(项){
return item;//您可以在这里实现您的逻辑
});
var html=“”;
_.each(无序,函数(项){html+=item+“
”;});
document.getElementById('output')。innerHTML=html;
}
对不起,你的问题是什么?是否也要在输出中显示存储的值?for(varitem in arrorded){document.write(item);}
