Cannot delete a row after I inserted it via button - HTML/JS

2022-05-04 10:19 Rowan imported from Stackoverflow

I have a table that I fill after a file upload. When I upload the file I can delete a selected row.

But when I add a row via click I cannot delete this row anymore.

The rows are created with the following:

function addTableRow(table, value)
{
 var table = document.getElementById("tablebody");
 var row = table.insertRow();
 var cell1 = row.insertCell(0);
 var cell2 = row.insertCell(1);

 cell1.innerHTML = value;
 cell2.innerHTML = '<img class="table-remove" style="height:15px;" src="images/delete.png">';
}

Click on Image to add row

 $('.table-add').click(function () {
    tableAddRow(document.getElementById("tablebody", "TEST"));
  });

Delete Row

$('.table-remove').click(function () {
    $(this).parents('tr').remove();
  });

I cannot delete a row that I added with a button click. It seems that $('.table-remove') is not found for a manually added row.

At this point I'm stuck. Thanks for any advice!

This happens because event binding happens on document load. Any elements that get inserted into the DOM after the inital document.ready won't be recognized by the code that has already run. If you dynamically insert/remove elements after page load, you need to bind your events to the new element when you insert it.
answered 2022-05-04 10:42 Haseeb Hassy
As the answer from Lalalena suggests, you need to bind the function with document so that it is registered in the DOM, like this:
```
$(document).on('click', '.table-remove', function () {
    $(this).parents('tr').remove();
});
```

how to change prettier format for react native

my code formatting prettier didn't works well for react native, i don't understand where to config it but it works well with flutter

from this code

      import { View, Text } from 'react-native'
    
    import React from 'react'
    
    export default function App() {
      return (
        <View>
    
    <Text>Apps</Text>   
</View>
      )
    }

it's formatted to this

import {
  View,
  Text
} from 'react-native'

import React from 'react'

export default function App() {
  return ( <
    View >

    <
    Text > Apps < /Text>


    <
    /View>
  )
}

Javascript: Change element class if button has a certain value
```
        <div class="main-div main-div2"> 
          <button id="update-btn" class="btn update-btn"> 
              Up to date
          </button>
        </div>
```
I want to make it so if update-btn has a value of "Up to date", change the div class from "main-div main-div2" to "main-div main-div3". Otherwise, if it's any other value, change it to "main-div main-div2"

What kind of loop would be good for this Javascript function too if I want it to be checking constantly?

Thank you.

How to clear user uploaded images if the limit of files exceeded in jquery
I have a simple form where a user can upload multiple images. I only want the user to upload 4 images at once, so I did the following:
```
$("#myfile").on("change", function() {
    if ($("#myfile")[0].files.length > 4) {
        alert("You can select only 4 images");
    } 
});
```
```
<input type="file" id="myfile" class="form-control" name="pimage[]" multiple="multiple">
```
This gives an alert when the user uploads more than 4 images but doesn't stop them from submitting the form.

Can anyone please tell me how to clear the user uploaded images if the limit exceeds or disable the submit button?

Whenever I try to add email on mysql server. My page is not responding. why?

I am a little bit confused. see the code below.

$('#submit').click(function() {
    $('#showdata').html($('#senddata').serialize()); /*Print all data that passed from form.*/
    $.ajax({
        url: "save.php",
        /* Here data store on mysql server without email and response to welcome.php. */
        type: "POST",
        /* if i want to add proper email format then data store in mysql but not response on welcome.php. */
        data: $('#senddata').serialize(),
        success: function(r) {
            alert("ok");
            $('#senddata').trigger('reset');
            window.location = 'welcome.php'; /*This is welcome page*/
        }
    })
})

I want to submit a form using the ajax post method. If I write any name instead of email then data is stored on the server and responding welcome.php. Whenever I write any name email then data is stored on the server but responding welcome.php. Here is 'save.php' code.

<?php
include('./config.php');
print_r($_POST);
    $name=$_POST['name'];
    $email=mysqli_real_escape_string($con,$_POST['email']);
    $pwd=$_POST['password'];
    $vill=$_POST['address'].$_POST['city'].$_POST['state'].$_POST['zip'];
    $insertdata="INSERT INTO `persons`(`name`,`email`,`pwd`,`vill`)VALUE('$name','$email','$pwd','$vill')";
    print_r($insertdata);
    if(mysqli_query($con,$insertdata)){
        echo "data added";
    }else{
        echo "not added";
    }

?>

Note: if I put my button <button class="btn btn-primary" id="submit">sign up</button> outside form then everting is right.

Export to excel with symbol

In JavaScript, how can I check if a symbol(for example €) is present in the HTML cell of a table and only in that case when exporting table to xls, delete the period if present and replace it with a comma in other cases?

Render tooltip outside/on top of a cell in html table?

I have a vue project that is utilizing the VueGoodTable Library. I am trying to put a conditional tool tip in data cells who's data is considered "abnormal" (this calc is done on the backend and is not important to my current issue).

Right now I am simply trying to show a tooltip on all cells inside of this table, but as the picture here shows, it is trapped inside of the cell itself and no amount of messing with the z-index has proven fruitful in getting the tooltip to show up over everything.

This table library uses slots to render it's cells, so it makes sense that whatever is in that template tag, is contained within that cell, but how can I break that case?

Any tips or ideas would be greatly appreciated!

EDIT: There seems to be Table Events in this library I am using, but I am still very unsure about how I could use this to render a tooltip in the rows. Table Events from Docs

EDIT 2: Here is a post that seemed promising for showing a table who's cells have a tooltip in them. However, their example uses roughly the same styling as I do, but their z-index seems to actually matter. Perhaps this is a limitation brought on by the library itself?

I've replicated a barebones version of my current table and tooltip component to check out what I've got.
