Suppose this is the prepare table below. and each of 3 row there was a textbox and beside them there where 2 buttons the + or add and - for delete. when i click + in a row, a new textbox will be generated and when i click - the textbox will delete. like the sample below:
Could anyone suggest the snippet for this step or procedure?
Thank you
you could write something on these lines:
<script type="text/javascript">
$(document).ready(function(){
var counter = 2;
$("#addButton").click(function () {
if(counter>10){
alert("Only 10 textboxes are allowed");
return false;
}
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter);
newTextBoxDiv.after().html('<label>Textbox #'+ counter + ' : </label>' +
'<input type="text" name="textbox' + counter +
'" id="textbox' + counter + '" value="" >');
newTextBoxDiv.appendTo("#TextBoxesGroup");
counter++;
});
$("#removeButton").click(function () {
if(counter==1){
alert("No more textbox to remove");
return false;
}
counter--;
$("#TextBoxDiv" + counter).remove();
});
});
</script>
If you do not want to create the div on the fly, you can find the id of your last table row, add 1 to it, create the table row, and then append the textbox creation html to it.
Assuming the html structure is as follows
<table border = "1">
<thead>
<tr><td> Text Boxes </td></tr>
</thead>
<tbody>
<tr><td><button class="add-text-box">+</button><button class="remove-text-box">-</button></td></tr>
<tr><td><button class="add-text-box">+</button><button class="remove-text-box">-</button></td></tr>
<tr><td><button class="add-text-box">+</button><button class="remove-text-box">-</button></td></tr>
</tbody>
the following jquery snippet should work
$(".add-text-box").click(function(){
$(this).parent().prepend(" <input class='text-box' /> <br>");
});
$(".remove-text-box").click(function(){
textboxes = $(this).parent().find('.text-box');
$(textboxes).last().remove();
if (textboxes.length === 0) {
$(this).siblings().remove();
$(this).remove();
}
});
