## Click To Load
This example shows how to implement click-to-load the next page in a table of data. The crux of the demo is
the final row:
```html
<tr id="replaceMe">
<td colspan="3">
<button class='btn' hx-get="/contacts/?page=2"
hx-target="#replaceMe"
hx-swap="outerHTML">
Load More Agents... <img class="htmx-indicator" src="/img/bars.svg">
</button>
</td>
</tr>
```
This row contains a button that will replace the entire row with the next page of
results (which will contain a button to load the *next* page of results). And so on.
{% include demo_ui.html.liquid %}
<script>

var dataStore = function(){

contactId++;
var idHash = "";
var possible = "ABCDEFG0123456789";
for( var i=0; i < 15; i++ ) idHash += possible.charAt(Math.floor(Math.random() * possible.length));
return { name: "Agent Smith", email: "void" + contactId + "@null.org", id: idHash }
}
return {
contactsForPage : function(page) {
var vals = [];
for( var i=0; i < 10; i++ ){
vals.push(generateContact());
