Step 2:
Now add below css styles in the head section to add a beauty.
<style>
@font-face{font-family: Lobster;src: url('Lobster.otf');}
body{width:750px;margin:0px auto;}
.space{margin-bottom: 4px;}
.txt{width:250px;border:1px solid #00BB64; height:30px;border-radius:3px;font-family: Lobster;font-size:20px;color:#00BB64;}
p{font-family: Lobster;font-size:35px; text-align:center;}
.but{width:250px;background:#00BB64;border:1px solid #00BB64;height:40px;border-radius:3px;color:white;margin-top:10px;}
</style>
Step 3:
Now we come into party of jQuery. First task is when we clicked on plus image it will dynamically add textboxes into the form.
var id = 2, txt_box;
$("#button_pro").on("click", ".add", function() {
var $this = $(this);
var parentId = $this.parent().attr("id");
if ($('#'+parentId).find('.remove').length == 0) {
$('#'+parentId).append('<img src="images/remove.png" class="remove"/>')
}
$this.remove();
txt_box =
'<div class="space" id="input_' +
id +
'" ><input type="text" name="val[]" class="left txt"/><img src="images/remove.png" class="remove"/><img class="add right" src="images/add.png" /></div>';
$("#button_pro").append(txt_box);
id++;
});when we clicked on the add image it will append textbox, plus image (addition) and minus image(Delete), as well we remove plus image next to the first text boxes. Also adds remove button near first textbox.
Step 4:
Now add following script to do delete operation when we clicked on the minus image(Delete).
$("#button_pro").on("click", ".remove", function() {
var parent = $(this).parent().prev().attr("id");
var parent_im = $(this).parent().attr("id");
$("#" + parent_im).slideUp("medium", function() {
$("#" + parent_im).remove();
if ($("#button_pro").find('input').length === 1) {
$("#button_pro").find('input').parent().find('.remove').remove();
}
if ($(".add").length < 1) {
$("#" + parent).append('<img src="images/add.png" class="add right"/> ');
}
});
});This will get the current parent id of the textbox and hide textbox.
var parent_im=$(this).parent().attr("id");
$("#"+parent_im).slideUp('medium');
Following script gets the current textbox previous container id.
var parent=$(this).parent().prev().attr("id");
Following script checks if there is no add image it’ll add image to the form.
if($('.add').length<1){
$("#"+parent).append('<img src="images/add.png" class="add right"/> ');
}
