How to prevent buttons from submitting forms
(20 answers)
Closed 4 years ago.
Good day!
My form has javascript functions for my buttons for adding rows from table and resetting the text fields in the form itself.
In my add button, I have an incrementing variable, rowCount, for counting the row. It works well and works what I expected. When I put it inside the <form></form> tag, it stuck at 2, doesn't increment and doesn't add rows at all.
Here's my code for our reference and also to be debugged. Thanks in advance!
var rowCount = 1;
function addRow() {
var table = document.getElementById('tblOrder');
rowCount = rowCount + 1;
var row = table.insertRow(rowCount);
var cell0 = row.insertCell(0);
var cell1 = row.insertCell(1);
var cell2 = row.insertCell(2);
var cell3 = row.insertCell(3);
var cell4 = row.insertCell(4);
var cell5 = row.insertCell(5);
cell0.innerHTML = "<input type='text'>";
cell1.innerHTML = "<input type='number'>";
cell2.innerHTML = "<input type='text'>";
cell3.innerHTML = "<input type='text'>";
cell4.innerHTML = "<input type='text'>";
cell5.innerHTML = "<input type='text'>";
alert(rowCount)
}
function resetForm() {
document.getElementById('orderForm').reset();
alert('All cleared!')
}

If buttons are put inside a form, they become submit buttons by default, meaning they submit the form when clicked. If the form doesn't have an action specified, it will be submitted to the same URL as the page, which results in the page being refreshed. This is what happens in your case.
To prevent a button from submitting the form, set its type to be a generic button instead of a submit button:
<button type="button"></button>

Displaying a table n times according to user input then having function to show/hide table according to row clicked

I want a table (table1) to be displayed n times according the number entered by the user in the input form. Then for each instance of this table the user should be able to click on each row and another relevant table should be displayed.
So far I can produce table1 n times according to user input. But then the function myFunction_disease is only applying to the first iteration of table1. I want each copy of table1 to controlled independently depending on what the user clicks.
Here is jsfiddle: https://jsfiddle.net/k0x4y6d2/1/
<div class="user_input_outer" id="num_of_conditions">
<div class= "content_text"> Number of conditions:</div>
<div class="user_input">
<input type="number" id="numb_conditions" onchange="myFunction_num_conditions();" min="2" max="1"> </div>
</div>
<div id=condition_detail>
</div>
function myFunction_num_conditions(x) {
container = document.getElementById('numb_conditions')
var number = container.value
for (var i = 0; i < number; i++) {
count = i+1
document.getElementById("condition_detail").innerHTML += 'Condition' + (i + 1);
let newdiv = document.createElement('div');
newdiv.innerHTML = "<table id=table1 class=table> <tr onclick='myFunction_disease(this)'><td>cardiac </td></tr> <tr onclick='myFunction_disease(this)'><td> respiratory </td></tr> <tr onclick='myFunction_disease(this)'><td>infection</td></tr></table><table id=table2 class=table> <tr onclick='myFunction_cardiac(this)'><td>MI </td></tr> <tr onclick='myFunction_cardiac(this)'> <td> valve disease </td></tr> <tr 'myFunction_cardiac(this)'><td>CCF</td></tr></table> <table id=table3 class=table> <tr onclick='myFunction_respiratory(this)'><td>COPD </td></tr> <tr onclick='myFunction_respiratory(this)'><td> asthma </td></tr> <tr onclick='myFunction_respiratory(this)'><td>bronchiectasis</td></tr></table><table id=table4 class=table> <tr onclick='myFunction_infectious(this)'><td>TB </td></tr> <tr onclick='myFunction_infectious(this)'><td> pneumonia </td></tr> <tr onclick='myFunction_infectious(this)'><td>cellulitis</td></tr></table>"
document.getElementById('condition_detail').appendChild(newdiv);

That's what you need. For adding more buttons and tables you can just simply add a new table and give a new class table$ (where $ is number, example: table4) and add a new button with data-table-show=$ attribute. That's all😉.
// Creating conditions
const numInput = document.getElementById('num'),
conditionForm = document.getElementById('condition-form'),
tablesContainer = document.getElementById('tables'),
conditionText = tablesContainer.innerHTML;
conditionForm.onsubmit = async function(e) {
e.preventDefault();
const numValue = Number(numInput.value);
await (tablesContainer.innerHTML += conditionText.repeat(numValue));
addEventListenersToButtons();
}
// Working with table filtering
function addEventListenersToButtons() {
let buttons = document.querySelectorAll('#tables tr.btn');
buttons.forEach(function(button, i) {
button.onclick = function() {
const tables = button.parentNode.parentNode.parentNode.querySelectorAll('.data-table');
tables.forEach(table => {
if (table.classList.contains(`table${button.dataset.tableShow}`)) {
table.classList.remove('hide')
} else {
table.classList.add('hide')
}
});
}
})
}
addEventListenersToButtons();

how to add html input with click on button

im trying to make a average grade calculator, now thats is going fine but now i want to add a row of inputs every time you click on a button, including html, javascript and also the assigned numbers increased by one. The inputs should go just under the existing ones and the calculate button should move along. I've been stuck at this point for a view days now, appreciate the help!
function getValue(el){
return (+document.getElementById(el).value)
};
function calculator() {
var weight1=getValue('weight-1');
var mark1=getValue('mark-1');
var grade1=weight1*mark1;
var weight2=getValue('weight-2');
var mark2=getValue('mark-2');
var grade2=weight2*mark2;
var totalWeight=weight1+weight2;
var totalGrade=grade1+grade2;
var finalGrade=totalGrade/totalWeight;
var display=document.getElementById('outputDiv');
display.innerHTML='Je gemiddelde is: ' +finalGrade.toFixed(2);
}

Instead of hard coding the ids of your inputs, you can get your weight and mark inputs with querySelectoryAll this will get you all your inputs no matter how many there are and then you can loop over the elements to get the values and then append a new input row with the id incremented by 1 to the tbody. Then the next time you call the function there will be one more input to loop over Here's an example based on your code:
function calculator() {
var weight = 0;
var mark = 0;
var weights = document.querySelectorAll('[id^=weight-]');
var grades = document.querySelectorAll('[id^=mark-]');
var trs = document.getElementsByTagName('tr');
var tBody = document.getElementsByTagName('tbody')[0];
var totalWeight = 0;
var totalGrade = 0;
for (var i = 0; i < weights.length; i++) {
totalWeight += +weights[i].value;
}
for (var i = 0; i < grades.length; i++) {
totalGrade += +grades[i].value;
}
var finalGrade=totalGrade/totalWeight;
var display = document.getElementById('outputDiv');
var newTr = document.createElement('TR');
newTr.innerHTML = `<td><input id="weight-${trs.length + 1}" type="text" size=2 maxlength="5" value=""></td><td><input id="mark-${trs.length + 1}" type="text" size=2 maxlength="5" value=""></td>`
tBody.appendChild(newTr);
display.innerHTML='Je gemiddelde is: ' +finalGrade.toFixed(2);

regarding your question and as Barmar said, StackOverflow requires the user to at least attempt the problem, when you run into a wall then you can ask away. I can't overrule this so I can't give you the actual code but I did manage to get it working quite quickly, if you understand Javascript it shouldn't be that difficult. I will try to give you hints on how it really should be structured.
Your Javascript needs to append all your form inputs from the beginning, set a variable equal to 0 and just append on button click a new input field onto the id="table" and increment by 1. This is as far as "I" personally can go to but if you show me that you attempted I can most definitively help you from there.
Best of luck!

You need to add type="button" since the default action in some browsers is a submit
<button type="button" ....>C</button>
<button type="button" ....>E</button>
Alternatively add ;return false to your onclick events like this:
onclick="add_Row(); return false"
to not submit the page
Better would be to assign the event handlers in an onload event but still you need to preventDefault the button's click event if it is not type="button"

Table with input text created by jquery how to save in mysql database

Please help me how to save in mysql database an inputted data in my dynamic table.
This is the html file.
index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>CodePen - Dynamic Table</title>

<div id="main">
<h1>Data Table</h1>
<table id="data" class="data-table data-table-horizontal data-table-highlight">

<tr>
<td><input type="text" /></td><td><input type="text" /></td><td><input type="text" /></td>
<td><input type="text" /></td>
<td><input type="text" /></td>
<td><a type="button" value="Delete" onclick="deleteRow(this)"><i class="fa fa-trash-o fa-fw"></i></a></td>
</tr>

<input type="button" value="Add" class="top-buffer" onclick="addRow('data')" />
</div>
</div>
<script src="dynamictable_js/index.js"></script>

This is javascript.
index.js:
function addRow(tableID) {
var table = document.getElementById(tableID);
var rowCount = table.rows.length;
var row = table.insertRow(rowCount);
var colCount = table.rows[0].cells.length;
for(var i=0; i<colCount; i++) {
var newRow = row.insertCell(i);
newRow.innerHTML = table.rows[0].cells[i].innerHTML;
newRow.childNodes[0].value = "";
}
}
function deleteRow(row) {
var table = document.getElementById("data");
var rowCount = table.rows.length;
if (rowCount > 1) {
var rowIndex = row.parentNode.parentNode.rowIndex;
document.getElementById("data").deleteRow(rowIndex);
}
else {
alert("Please specify at least one value.");
}
}
This is the css.

add auto-increment or timestamp - javascript, jstorage

I'm trying to implement jstorage on my website. I'm new to JavaScript and thus need some help here.
jstorage requires Key and Value to be given for each saved row.
I would like Key to be filled in automatically with either with auto-increment value or timestamp, whichever is easier - values need to be unique.
Here is the whole code:
