错误(TypeError:无法读取null(...)的属性“样式”)在调用placeAt()方法时弹出 [英] Error (TypeError: Cannot read property 'style' of null(…)) pop out whenever placeAt() method is called
问题描述
以下代码在我的其他项目中正常工作,但当我将对象放在当前项目中的div时,它会不断弹出此错误。有没有必要注意placeAt()方法?
The following codes works fine in my other project but it keep pop out this error when i placing a object to div in current project. is there any concern must be aware for placeAt() method?
rest.then(function(response){
var dataset = response.data;
array.forEach(dataset, function(single, i){
if(dataset[i].favorite){
favorite++;
}
if(dataset[i].status == "OO"){
outOfService++;
}
});
try{
var dashBoardShortCutCell = new DashBoardShortCutCell();
dashBoardShortCutCell.construct("favorite", favorite);
dashBoardShortCutCell.placeAt(context.shortCutContainerNode);
}catch(err){
console.log(err);
}
dashBoardShortCutCell = new DashBoardShortCutCell();
dashBoardShortCutCell.construct("Out of Service", outOfService);
try{
dashBoardShortCutCell.placeAt(context.shortCutContainerNode);
}catch(err){
console.log(err);
}
}, function(err){
console.log("Error", err);
}, function(evt){
});
然后显示控制台:
DashboardPage.js:85 TypeError:无法读取属性'style'为null(...)
DashboardPage.js:85 TypeError: Cannot read property 'style' of null(…)
DashboardPage.js:95 TypeError:无法读取属性'style'为null )
DashboardPage.js:95 TypeError: Cannot read property 'style' of null(…)
推荐答案
无法读取属性style为null
"Cannot read property 'style' of null"
从错误本身已经提到的根本原因。您的JavaScript正在尝试对未定义/空节点进行一些样式。请确保您正确定义了目标节点
From the error itself already mentioned the root cause. Your JavaScript is trying to do some styling to undefined/null node. Please make sure you defined properly the target node
