Quill Editor: Cleverly implement text label nesting
When doing text annotation in Quill Editor, it is crucial to handle the nesting effect of overlapping annotations. This article provides a solution to effectively solve the situation where multiple annotation index overlaps.
First, we review common requirements and code snippets:
Sample data:
const response = {
"errorwordlist": [
{
"alertmessage": "It is recommended to use "NPC Standing Committee/NPC Standing Committee Members/NPC Standing Committee Members (please choose according to the actual situation)\" Replace "NPC Standing Committee Members\"",
"replacetext": "National Congress Standing Committee/National Congress Standing Committee Member/National Congress Standing Committee Member (please choose according to actual situation)",
// ... other properties
"start": 9,
"end": 13,
"id": 1
},
{
"alertmessage": "It is recommended to use standardized words\"Provincial People's Congress Standing Committee\"",
"replacetext": "Provincial People's Congress Standing Committee",
// ... other properties
"start": 8,
"end": 13,
"id": 2
}
],
// ... other properties
};
Improved annotation method:
The original annotation method has defects and cannot handle nested annotations. We need to optimize the algorithm to ensure that overlapping annotation areas are handled correctly.
Core idea:
- Sort: Sort
errorwordlistin ascending order according tostartindex. - Iterative processing: Iterate over the sorted array and process each annotation in turn.
- Offset: For non-first labels, the length of the previous label needs to be considered and the correct
startoffset is calculated.
Improved code:
const sortedErrorList = response.errorwordlist.sort((a, b) => a.start - b.start);
sortedErrorList.forEach((item, index) => {
let length = item.end - item.start;
if (length > 0) {
let startOffset = item.start;
if (index > 0) {
// Calculate the offset and avoid repeated labeling startOffset = sortedErrorList[index - 1].end - sortedErrorList[index - 1].start;
}
this.editor.updateContents([
{ retain: startOffset },
{ retain: length, attributes: { click: item } }
]);
}
});
Through this method, we can effectively handle overlapping annotations to achieve the correct nesting effect. This avoids possible label overrides or misalignment problems in the original code. The final rendered annotation results will accurately reflect the start and end positions of each annotation in the data, even if they overlap.
Custom Blot (optional optimization):
For better maintainability and scalability, you can consider using custom Blots to implement label styles. This part of the code can be adjusted and optimized according to actual needs.
Through the above improvements, the Quill Editor can perfectly handle nested text annotations and improve the user experience.
