Visjs timeline edit content item template - vis.js

Question

I'd like to be able to edit the content attribute of visjs timeline items in the timeline itself. However, when I use an input as part of a template, it doesn't appear to receive any mouse events; I can't click in it and type anything, and clicking buttons doesn't work, either. Buttons appear to get the mouseover event, though:
function test(item) {
alert('clicked');
}
var options = {
minHeight: '100%',
editable: true,
moveable: false,
selectable: false,
orientation: 'top',
min: new Date('2015-01-01'),
max: new Date('2015-12-31'),
zoomMin: 1000 * 4 * 60 * 24 * 7,
margin: {
item: 10,
axis: 5
},
template: function(item) {
return '<div onClick="test"><input value="click in the middle"></input><button onClick="test">test</button></div>'
}
};
/* create timeline */
timeline.on('click', function (properties) {
var target = properties.event.target;
if(properties.item) properties.event.target.focus();
});

Edit: Code above CodePen example have been updated to use the click event to focus on the input, but all other normal mouse behavior is missing. Keyboard events appear to function normally.

Answer 1

To get a reaction with a click on a timeline element, you can use the library's own events (see events on doc and this exemple on website).
On your example, you could do something like this among other possible solutions in pure javascript including...
// Configuration for the Timeline
var options = {
minHeight: '100%',
editable: true,
moveable: false,
selectable: false,
orientation: 'top',
min: new Date('2015-01-01'),
max: new Date('2015-12-31'),
zoomMin: 1000 * 4 * 60 * 24 * 7,
margin: {
item: 10,
axis: 5
},
template: function(item) {
return '<div id="test-div"><input placeholder="hey" type="text" id="inputTest" ><button id="test-button">test</button></div>'
}
};
// Create a Timeline
var timeline = new vis.Timeline(container, null, options);
timeline.setGroups(groups);
timeline.setItems(items);
timeline.on('click', function (properties) {
var target = properties.event.target;
if(properties.item) alert('click on' + target.id);
});
UPDATED
It is difficult to know exactly what you want to do because there are several possible solutions anyway.
Eventually, I propose another snippet below and a codepen updated.... but will it meet your need, not sure ?
2nd UPDATE (for another work track, see comments)
// Configuration for the Timeline
var options = {
minHeight: '100%',
editable: true,
moveable: false,
selectable: false,
orientation: 'top',
margin: {
item: 10,
axis: 5
},
template: function(item) {
return '<div><input placeholder="edit me..." type="text"></input><button>send value</button></div>'
}
};
// Create a Timeline
var timeline = new vis.Timeline(container, null, options);
timeline.setGroups(groups);
timeline.setItems(items);
timeline.on('click', function(properties) {
var target = properties.event.target;
var item = items.get(properties.item);
console.log(properties.event);
// if (properties.item && target.tagName === "DIV") focusMethod(target);
if (properties.item && target.tagName === "INPUT") target.focus();
if (properties.item && target.tagName === "BUTTON") getInputValue(item, target);
});
focusMethod = function getFocus(target) {
// target.insertAfter("BUTTON");
target.firstChild.focus();
}
getInputValue = function getValue(item, target) {
target.focus();
var inputValue = (target.parentNode.firstChild.value) ? target.parentNode.firstChild.value : "no value entered ";
alert("Input value : " + inputValue + " => send by: " + item.content)
}
