It would be great if you would wrap ellipsis character into span with class to enable styling it differently than the rest of the text.
Sorry if this sounds kind of stupid, I should know the answer, but how do I go about adding something like this into a non Node application?
Suppose I just had raw HTML page... is there a way I can just download minified version or have some kind of CDN to reference?
I have an issue where any text that apply line-clamp to gets truncated to just one line in smaller (< 968px) viewports even though I've set it the option to three lines. Works fine for viewports > 968px. Any ideas what could be causing this?
I've confirmed that the line-clamp method correctly calculates the line-height of the text element.
For the elements which have line-height written as a float number there is an issue in calculation, due to truncation of decimal part.
e.g. for line-height: 18.5667px
parseInt('18.5667px', 10) // 18
parseFloat('18.5667px') // 18.5667
Suggestion is to update how maximumHeight
is calculated:
module.exports = function (rootElement, lineCount, options) {
...
var maximumHeight = Math.round(
(lineCount || 1) *
parseFloat(window.getComputedStyle(rootElement).lineHeight))
Please add file bundle.js
For app frameworks like Angular, HTML elements can be generated and apply effects (like line-clamping) before those HTML elements are actually rendered into the DOM. This means that virtually all values from window.getComputedStyles
are empty strings which makes this line of code produce NaN
as a value.
In truncateTextNode
, the comparison of the text node's scroll height to the maximum height now compares a number (zero) to NaN
, which is always false. This never breaks out of the loop and every word in the text node gets deleted. This means that text node content that gets initialized before an HTML element is inserted into the DOM will be deleted completely.
Can lineHeight
be added as an option to the exported function so that frameworks can inject expected line heights before components are added to the DOM? Some other alternative could be acceptable, so long as the case of a zero-height element with no computed line-height value can be handled.
module.exports = function (rootElement, lineCount, options) {
...
var maximumHeight =
(lineCount || 1) * parseInt(window.getComputedStyle(rootElement).lineHeight || options.lineHeight, 10);
