如何使用 javaScript 在按鈕單擊時從表中刪除特定行

Question

我正在嘗試在單擊按鈕時從表中刪除特定行。當我單擊刪除按鈕時，它會刪除第一行，而不是特定的選定行。

這是我的代碼

JavaScript

 let srN=1;
function getData(){
   
 let Name= document.getElementById("txtName").value;
 let fName=document.getElementById("txtFname").value;
 let mail=document.getElementById("txtEmail").value;
let password=document.getElementById("txtPassword").value;
let address=document.getElementById("txtAddress").value;
let city=document.getElementById("txtCity").value;
let work=document.querySelector('input[name="gridRadios"]:checked').value
let skills=document.getElementById("txtSkills").value;
let experience=document.getElementById("txtExperience").value;
let message=document.getElementById("msg").value;

let tblData=document.getElementById("tbl");

 let data="<tr id=tr'srN'><td>"+srN+"</td><td>"+Name+"</td><td>"+fName+"</td><td>"+mail+"</td> <td>"+password+"</td><td>"+address+"</td><td>"+city+"</td><td>"+work+"</td><td>"+skills+"</td><td>"+experience+"</td><td>"+message+"</td><td><button id='delRow"+srN+"' onclick='remove("+srN+")'>Delete</button></td></tr>";
 srN+=1;
 tblData.innerHTML+=data;
 document.getElementById("txtName").value=" ";
document.getElementById("txtFname").value=" ";
document.getElementById("txtEmail").value=" ";
document.getElementById("txtPassword").value=" ";
document.getElementById("txtAddress").value=" ";
document.getElementById("txtCity").value=" ";
document.querySelector('input[name="gridRadios"]:checked').value=" ";
document.getElementById("txtSkills").value=" ";
document.getElementById("txtExperience").value=" ";
document.getElementById("msg").value=" ";

document.getElementById("txtName").focus();
}

function remove(){
    
    document.getElementById("tr'srN'").remove(); 
   
}

Answer 1

將您的data線更改為：

let data="<tr id=tr"+srN+"><td>"+srN+"</td><td>"+Name+"</td><td>"+fName+"</td><td>"+mail+"</td> <td>"+password+"</td><td>"+address+"</td><td>"+city+"</td><td>"+work+"</td><td>"+skills+"</td><td>"+experience+"</td><td>"+message+"</td><td><button id='delRow"+srN+"' onclick='remove("+srN+")'>Delete</button></td></tr>";

並將您的刪除行更改為：

document.getElementById("tr"+srN).remove();

根據提供的代碼，

let srN=1;
function getData(){
   
let Name= document.getElementById("txtName").value;
let fName=document.getElementById("txtFname").value;
let mail=document.getElementById("txtEmail").value;
let password=document.getElementById("txtPassword").value;
let address=document.getElementById("txtAddress").value;
let city=document.getElementById("txtCity").value;
let work=document.querySelector('input[name="gridRadios"]:checked').value
let skills=document.getElementById("txtSkills").value;
let experience=document.getElementById("txtExperience").value;
let message=document.getElementById("msg").value;

let tblData=document.getElementById("tbl");
// changes to how tr id attribute was set
 let data="<tr id=tr'"+srN+"'><td>"+srN+"</td><td>"+Name+"</td><td>"+fName+"</td><td>"+mail+"</td> <td>"+password+"</td><td>"+address+"</td><td>"+city+"</td><td>"+work+"</td><td>"+skills+"</td><td>"+experience+"</td><td>"+message+"</td><td><button id='delRow"+srN+"' onclick='remove("+srN+")'>Delete</button></td></tr>";
 srN+=1;
 tblData.innerHTML+=data;
 document.getElementById("txtName").value=" ";
document.getElementById("txtFname").value=" ";
document.getElementById("txtEmail").value=" ";
document.getElementById("txtPassword").value=" ";
document.getElementById("txtAddress").value=" ";
document.getElementById("txtCity").value=" ";
document.querySelector('input[name="gridRadios"]:checked').value=" ";
document.getElementById("txtSkills").value=" ";
document.getElementById("txtExperience").value=" ";
document.getElementById("msg").value=" ";

document.getElementById("txtName").focus();
}

// changes made on remove function to accept the srN
// and thus remove by srN of individual table row
function remove(srN){
    document.getElementById("tr" + srN).remove(); 
   
}
