[英]Link in ChartJS tooltip not clickable
I've added an <a>
tag to my custom tooltip, but when I click on it it doesn't redirect to the href.我已经在我的自定义工具提示中添加了一个<a>
标签,但是当我点击它时它不会重定向到 href。
I copied the custom tooltip exactly from these docs .我完全从这些文档中复制了自定义工具提示。 I'll also paste the code below for ease.为了方便起见,我还将粘贴下面的代码。
Then, I added the following innerHTML:然后,我添加了以下 innerHTML:
var tableRoot = tooltipEl.querySelector("table");
tableRoot.innerHTML = innerHtml + '<a href="www.google.com">Click Here</a>';
However, the link isn't clickable - it doesn't even trigger cursor: pointer
like a normal <a>
tag.但是,该链接不可点击 - 它甚至不会触发cursor: pointer
,就像普通的<a>
标签一样。
The full custom tooltip code:完整的自定义工具提示代码:
custom: function(tooltipModel) {
// Tooltip Element
var tooltipEl = document.getElementById('chartjs-tooltip');
// Create element on first render
if (!tooltipEl) {
tooltipEl = document.createElement('div');
tooltipEl.id = 'chartjs-tooltip';
tooltipEl.innerHTML = '<table></table>';
document.body.appendChild(tooltipEl);
}
// Hide if no tooltip
if (tooltipModel.opacity === 0) {
tooltipEl.style.opacity = 0;
return;
}
// Set caret Position
tooltipEl.classList.remove('above', 'below', 'no-transform');
if (tooltipModel.yAlign) {
tooltipEl.classList.add(tooltipModel.yAlign);
} else {
tooltipEl.classList.add('no-transform');
}
function getBody(bodyItem) {
return bodyItem.lines;
}
// Set Text
if (tooltipModel.body) {
var titleLines = tooltipModel.title || [];
var bodyLines = tooltipModel.body.map(getBody);
var innerHtml = '<thead>';
titleLines.forEach(function(title) {
innerHtml += '<tr><th>' + title + '</th></tr>';
});
innerHtml += '</thead><tbody>';
bodyLines.forEach(function(body, i) {
var colors = tooltipModel.labelColors[i];
var style = 'background:' + colors.backgroundColor;
style += '; border-color:' + colors.borderColor;
style += '; border-width: 2px';
var span = '<span style="' + style + '"></span>';
innerHtml += '<tr><td>' + span + body + '</td></tr>';
});
innerHtml += '</tbody>';
var tableRoot = tooltipEl.querySelector('table');
tableRoot.innerHTML = innerHtml;
}
// `this` will be the overall tooltip
var position = this._chart.canvas.getBoundingClientRect();
// Display, position, and set styles for font
tooltipEl.style.opacity = 1;
tooltipEl.style.position = 'absolute';
tooltipEl.style.left = position.left + window.pageXOffset + tooltipModel.caretX + 'px';
tooltipEl.style.top = position.top + window.pageYOffset + tooltipModel.caretY + 'px';
tooltipEl.style.fontFamily = tooltipModel._bodyFontFamily;
tooltipEl.style.fontSize = tooltipModel.bodyFontSize + 'px';
tooltipEl.style.fontStyle = tooltipModel._bodyFontStyle;
tooltipEl.style.padding = tooltipModel.yPadding + 'px ' + tooltipModel.xPadding + 'px';
tooltipEl.style.pointerEvents = 'none';
}
Remove去掉
tooltipEl.style.pointerEvents = 'none';
and any of theese from CSS以及 CSS 中的任何一个
pointer-events: none;
I've faced the very problem myself, so I tried to remove this line:我自己也遇到过这个问题,所以我试图删除这一行:
tooltipEl.style.pointerEvents = 'none';
but it didn't work as expected - every time I hovered over the tooltip it disappeared.但它没有按预期工作 - 每次我将鼠标悬停在工具提示上时它都会消失。
Then, I tried this:然后,我尝试了这个:
Keep the line above just as it is;保持上面的线不变;
Modify events
prop of the options
.修改options
的events
属性。 (See docs ). (见文档)。 By doing this, you actually remove 'mouseout' event from the default config.通过这样做,您实际上从默认配置中删除了 'mouseout' 事件。
const options = { maintainAspectRatio: false, events: ['mousemove', 'click', 'touchstart', 'touchmove'], plugins: { tooltip: { enabled: false, external: externalTooltipHandler }, legend: { display: false } }, }
Then, remove pointer-events from the sole clickable element of the tooltip.然后,从工具提示的唯一可点击元素中删除指针事件。 In my case, it is li
element.在我的例子中,它是li
元素。 I did this with CSS. li { pointer-events: auto; }
我用 CSS.li li { pointer-events: auto; }
li { pointer-events: auto; }
When 1-3 steps are completed, the external tooltip is supposed to behave as expected AND the link elements contained in that tooltip should be clickable.完成 1-3 个步骤后,外部工具提示的行为应该符合预期,并且该工具提示中包含的链接元素应该是可点击的。
