javascript - Javascript 消息

Question

我在修复我的 JS 代码时遇到了一些问题。在代码片段中你可以看到我的程序，

现在单击第一个复选框。底部会出现一条消息，只要我在其中输入一个数字，该消息就会消失，并且文本框不应禁用...

当我单击第二个复选框时，该消息应附加到上一个复选框，但它只是覆盖...然后使用与前一个相同的值...

谁能给我一些想法？应该是测试功能有问题...

先感谢您。

function test(el)
{
    divOutput = document.getElementById("msgbox2");
    strValideer = "<ul>";
    var txt = document.getElementById(el.id.replace('chk', 'txt'))
    if (el.checked === true ) {
        txt.disabled = false;
        if(txt.value==="")
        {
            strValideer += "<li><b>" + txt.name + ": </b>verplicht veld</li>";
        }
        }
    else if (el.checked === false)
    {
        txt.disabled = true;
      return;

    }

    strValideer += "</ul>";
    divOutput.innerHTML = strValideer;
}

Answer 1

您需要先检查孩子是否有节点。检查它现在可以工作的功能

var list = [];
function test(el) {
    divOutput = document.getElementById("msgbox2");
    strValideer = "<ul>";
    var txt = document.getElementById(el.id.replace('chk', 'txt'));
    if (el.checked === true) {
        txt.disabled = false;
        if (txt.value === "") {
            list.push(txt.name);
        }
    }
    else if (el.checked === false) {
        txt.disabled = true;
        list.splice(list.indexOf(txt.name), 1);
    }
    for (var i = 0; i < list.length; i++) {
        strValideer += "<li><b>" + list[i] + ": </b>verplicht veld</li>";
    }
    strValideer += "</ul>";
    divOutput.innerHTML = strValideer;
}
