请教js动态增加表格的每个字段为input,但是不能提交值
一:动态增加行的js代码
var index;
index = 1;
function insertRow(){
var s1 = "";
var s2 = "";
var s3 = "";
var s4 = "";
var s5 = "";
var s6 = "";
var s7 = "";
var s8 = "";
var s9 = "";
var s10 = "";
var table = document.getElementById('table1');
row = table.insertRow(index);
/*insertRow() 方法用于在表格中的指定位置插入一个新行。
语法tableObject.insertRow(index)
返回值 返回一个 TableRow,表示新插入的行。
说明
该方法创建一个新的 TableRow 对象,表示一个新的
标记,并把它插入表中的指定位置。
新行将被插入 index 所在行之前。若 index
等于表中的行数,则新行将被附加到表的末尾。
如果表是空的,则新行将被插入到一个新的
num = document.getElementById("tbl").rows.length;
R = tbl.insertRow(num-2); //倒数第2行插入
抛出
若参数 index 小于 0 或大于等于表中的行数,该方法将抛出代码为 INDEX_SIZE_ERR 的 DOMException 异常。*/
row.id = "tr" + index;
c1 = row.insertCell(-1);//插入列td,一个一个插入,代码用innerHTML写入
c1.innerHTML = s1;
c2 = row.insertCell(-1);
c2.innerHTML = s2;
c3 = row.insertCell(-1);
c3.innerHTML = s3;
c4 = row.insertCell(-1);
c4.innerHTML = s4;
c5 = row.insertCell(-1);
c5.innerHTML = s5;
c6 = row.insertCell(-1);
c6.innerHTML = s6;
c7 = row.insertCell(-1);
c7.innerHTML = s7;
c8 = row.insertCell(-1);
c8.innerHTML = s8;
c9 = row.insertCell(-1);
c9.innerHTML = s9;
c10 = row.insertCell(-1);
c10.innerHTML = s10;
}
function delRow(index){
var table = document.getElementById('table1');
table.deleteRow(document.getElementById("tr" + index).rowIndex);
this.index = this.index - 1;

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
