我如何（）使用多输入函数和带有varibele更改的id [英] How do I for() function with multi input and the id with a varibele change

问题描述

for(i=0; i<singels.length ; i++){




var count = i+'"';
var $singel = '"#singel';



$($singel+count).on('change', function() {
var val = $($singel+count).val();
var someSingel = val*singelsvalue;
$("span").text(someSingel.toFixed(2));
someSingel = someSingel * val;
});


$("#box #singels form ul").append("<li>"
+ singels[i] + " " + singelsvalue[i]+ "          " +
'<input class="input" id="singel'+i+'" name="singel'+i+'" type="text" placeholder="stake "><p>To Return  <span>'+ someSingel +'<span></p></li>');
}

我的尝试：


和所有循环需要.append in form-> ul->新的li与id =singel+ [i]

它的工作正常，但只是在anoteh线工作的我有一些问题

i有一些数组有这个数组所有循环推送ID中的项目

和dann我需要精确地输入另一个id wehen用户输入char代码

.keyup（）取char并输入类似输入 - > 250

输入* val（//来自阵列的这个val，即[3]）= 750

现在我需要我做的工作

cosdole给我错误

now i need now what i make worng
cosdole give me error "

Uncaught Error: Syntax error, unrecognized expression: 

推荐答案

singel ='#singel';

singel = '"#singel';

（

singel + count）.on（'change'，function（）{
var val =

singel+count).on('change', function() { var val =
