Question

I get data using ajax with button load more, and if it's not have next pages, it will render "all data has been displayed"
index.html
<div class="panel-body">
<div id="display-data">
<span id="loading-help">Loading data. . .</span>
</div>
</div>
<script>
var page = 1
$(document).ready(function(){
$.get("{% url 'account:profile' %}?param=get_data&page="+page,
function(data){
$("#display-data").append(data)
$("#loading-help").remove()
page++
})
</script>
data-ajax.html
{% for data in datas %}
<div class="list-trx-data">
<div class="row align-items-center">
<div class="col-md-8">
<div class="row align-items-center">
<div class="col-md-4 col-sm-12 col-12 data-date">
{{data.get_formatted_date}}</div>
<div class="col-md-8 col-sm-12 col-12 data-name">
{{data.get_data}}</div>
</div>
</div>
<div class="col-md-4">
<div class="row align-items-center">
<div class="col-md-6 col-8 data-amount">
{{data.get_formatted_amount}}</div>
<div class="col-md-6 col-4 ">
<div class="data-progress">
<div class="pg-bar" style="width:
{{data.get_data.get_progress_str}}"></div>
</div>
</div>
</div>
</div>
</div>
</div>
{% endfor %}
{% if datas.has_other_pages %}
{% if datas.has_next %}
<a href="javascript:void(0)" class="btn btn-ghost btn-block mt-2"
id="load-more-btn">Load More</a>
{% else %}
<a href="javascript:void(0)" class="btn btn-ghost btn-block mt-2"
id="load-more-btn">All data has been displayed</a>
{% endif %}
{% endif %}
<script>
$("#load-more-btn").click(function(){
$.get("{% url 'account:profile' %}?param=get_data&page="+page,

$("#display-data").append(data)
page++
})
})
</script>
I have try it but it's render all button
before click load more
after click load more

Firstly, don't place javascript in the data-ajax.html. All the javascript code should be placed in index.html, where all the logics need to be implemented. If there is not other data, data-ajax.html returned should be empty.
data-ajax.html
{% for data in datas %}
<div class="list-trx-data">
<div class="row align-items-center">
<div class="col-md-8">
<div class="row align-items-center">
<div class="col-md-4 col-sm-12 col-12 data-date">
{{data.get_formatted_date}}</div>
<div class="col-md-8 col-sm-12 col-12 data-name">
{{data.get_data}}</div>
</div>
</div>
<div class="col-md-4">
<div class="row align-items-center">
<div class="col-md-6 col-8 data-amount">
{{data.get_formatted_amount}}</div>
<div class="col-md-6 col-4 ">
<div class="data-progress">
<div class="pg-bar" style="width:
{{data.get_data.get_progress_str}}"></div>
</div>
</div>
</div>
</div>
</div>
</div>
{% endfor %}
{% if datas.has_other_pages %}
{% if datas.has_next %}
<a href="javascript:void(0)" class="btn btn-ghost btn-block mt-2"
id="load-more-btn">Load More</a>
{% endif %}
In your index.html, check if ajax call returned anything, if not, then change button text, else, remove the button element, since your data-ajax.html already has button based on {% if datas.has_other_pages %}.
index.html
<div class="panel-body">
<div id="display-data">
<span id="loading-help">Loading data. . .</span>
</div>
</div>
<script>
$(document).ready(function(){
var page = 1; //page defined in $(document).ready()
function getData(){
$.get("{% url 'account:profile' %}?param=get_data&page="+page, function(data){
$("#loading-help").remove();
if (data){
// data was received
$("#loading-help").remove();
$("#load-more-btn").remove(); # remove the load button if data is there.
$("#display-data").append(data);
page++;
} else {
$("#load-more-btn").text("All data has been displayed"); # else, change button text.
}
});
}
getData(); //Load data for the first time.
$("#load-more-btn").click(function(){
getData(); //Load data on button click.
});
</script>
