1.
或者  标签崩溃问题

解决方法 HTMLElemen类中

var words = this._getWords();

if (words == null && (!this._children || this._children.length == 0))

return false;

if (words) {

for (var i = 0, n = words.length; i < n; i++) {

out.push(words[i]);

}

}

if (this._children)

this._children.forEach(function (o, index, array) {

var _style = o._style;

if(_style)

{

_style._enableLayout && _style._enableLayout() && o._addToLayout(out);

}

else

{

o._addToLayout &&  o._addToLayout(out);

}

});

return true;

}

添加了

if(_style)

{

_style._enableLayout && _style._enableLayout() && o._addToLayout(out);

}

else

{

o._addToLayout &&  o._addToLayout(out);

} 这个保护

2.富文本超链接无法换行 workLines中索引i没有初始化为0

workLines(wordList, g, recList) {

var cssStyle = this.style;

var hasLine;

hasLine = cssStyle.textDecoration != "none";

var i = 0, len;

len = wordList.length;

var tStartWord;

tStartWord = wordList[i];

var tEndWord;

tEndWord = tStartWord;

if (!tStartWord)

return;

var tword;

for (i = 1; i < len; i++) {

tword = wordList[i];

if (tword.y != tStartWord.y) {

this.createOneLine(tStartWord, tEndWord, hasLine, g, recList);

tStartWord = tword;

tEndWord = tword;

}

else {

tEndWord = tword;

}

}

this.createOneLine(tStartWord, tEndWord, hasLine, g, recList);

}

3. 超链接的区域无法支持鼠标事件的mouseover和 mouseout 因此可以扩展一下

第一步 修改此类：

class HTMLHitRect {

constructor() {

this.rec = new Laya.Rectangle();

this.isMouseOver = false;

this.reset();

}

reset() {

this.rec.reset();

this.href = null;

this.isMouseOver = false;

return this;

}

getIsMouseOver()

{

return this.isMouseOver;

}

setIsMouseOver(val)

{

this.isMouseOver = val;

}

recover() {

Laya.Pool.recover("HTMLHitRect", this.reset());

}

static create() {

return Laya.Pool.getItemByClass("HTMLHitRect", HTMLHitRect);

}

}

第二步 class HTMLDivElement 构造中监听一下

this.on(Laya.Event.MOUSE_OVER, this, this._onMouseOver);

this.on(Laya.Event.MOUSE_OUT, this, this._onMouseOut);

this.on(Laya.Event.MOUSE_MOVE, this, this._onMouseMove);

增加如下3个方法

_onMouseOver()

{

var tX = this.mouseX;

var tY = this.mouseY;

var i, len;

var tHit;

len = this._recList.length;

for (i = 0; i < len; i++) {

tHit = this._recList[i];

if (tHit.rec.contains(tX, tY)) {

tHit.setIsMouseOver(true);

this.event("HREF_MOUSE_OVER", [tHit.href]);

}

}

}

_onMouseMove()

{

var tX = this.mouseX;

var tY = this.mouseY;

var i, len;

var tHit;

len = this._recList.length;

for (i = 0; i < len; i++) {

tHit = this._recList[i];

if (tHit.rec.contains(tX, tY)) {

if(!tHit.getIsMouseOver())

{

tHit.setIsMouseOver(true);

this.event("HREF_MOUSE_OVER", [tHit.href]);

}

}

else

{

if(tHit.getIsMouseOver())

{

tHit.setIsMouseOver(false);

this.event("HREF_MOUSE_OUT", [tHit.href]);

}

}

}

}

_onMouseOut()

{

var tX = this.mouseX;

var tY = this.mouseY;

var i, len;

var tHit;

len = this._recList.length;

for (i = 0; i < len; i++) {

tHit = this._recList[i];

if (tHit.getIsMouseOver() && !tHit.rec.contains(tX, tY)) {

tHit.setIsMouseOver(false);

this.event("HREF_MOUSE_OUT", [tHit.href]);

}

}

}
