## Interaction
It is possible to bind a click event to a task, the click can lead to either a javascript callback or to a link which will be opened in the current browser tab. **Note**: This functionality is disabled when using `securityLevel='strict'` and enabled when using `securityLevel='loose'`.
```
click taskId call callback(arguments)
click taskId href URL
```
* taskId is the id of the task
* callback is the name of a javascript function defined on the page displaying the graph, the function will be called with the taskId as the parameter if no other arguments are specified..
Beginners tip, a full example using interactive links in an html context:
```
<body>
<div class="mermaid">
gantt
dateFormat YYYY-MM-DD
section Clickable
Visit mermaidjs :active, cl1, 2014-01-07, 3d
Print arguments :cl2, after cl1, 3d
Print task :cl3, after cl2, 3d
click cl1 href "https://mermaidjs.github.io/"
click cl2 call printArguments("test1", "test2", test3)
click cl3 call printTask()
</div>
<script>
var printArguments = function(arg1, arg2, arg3) {
alert('printArguments called with arguments: ' + arg1 + ', ' + arg2 + ', ' + arg3);
}
var printTask = function(taskId) {
alert('taskId: ' + taskId);
}
var config = {
startOnLoad:true,
securityLevel:'loose',
};
mermaid.initialize(config);
</script>
</body>
```
