Ignore errors and continue running javascript in IE?
提问by Rob
I've got a JIT Spacetree on my webpage, and IE doesn't like a few lines. If I open the developer tools, and tell it to run through them, it looks great and loads everything as it should.
我的网页上有一个 JIT Spacetree，而 IE 不喜欢几行。如果我打开开发人员工具，并告诉它运行它们，它看起来很棒，并且可以按预期加载所有内容。
Is there any way I can get it to just say "You know what, these errors aren't really deal breakers, let's keep on going here"? The two further indented lines are the offenders, as well as something in jQuery 1.6.4 (will be trying 1.7.1) with either $.getJSON or $.parseJSON
有什么办法可以让它只是说“你知道吗，这些错误并不是真正的交易破坏者，让我们继续在这里”？两个进一步缩进的行是违规者，以及 jQuery 1.6.4（将尝试 1.7.1）中的一些东西，带有 $.getJSON 或 $.parseJSON
var style = label.style;
style.width = node.data.offsetWidth;
style.height = node.data.offsetHeight;
style.cursor = 'pointer';
style.color = '#fff';
style.fontSize = '0.8em';
style.textAlign= 'center';
},

wrap the offending code in a try/catch, and don't do anything in the catch.
将违规代码包装在 try/catch 中，并且不要在 catch 中执行任何操作。

IE is "allergic" in defining an object and leave a comma at the last attribute.
IE 在定义对象时“过敏”，并在最后一个属性处留一个逗号。
Bad:
坏的：
var apple = { color : "yellow",
taste : "good", };
Good:
好的：
var apple = { color : "yellow",
taste : "good" };

You could use a try catch statement.
您可以使用 try catch 语句。
var style = label.style;
try
{
style.width = node.data.offsetWidth;
style.height = node.data.offsetHeight;
}
catch(err) { /* do nothing */ }
style.cursor = 'pointer';
style.color = '#fff';
style.fontSize = '0.8em';
style.textAlign= 'center';

Wrap those offending code inside a try { } catch (e) {}block and you should be good to go..
将那些有问题的代码包装在一个try { } catch (e) {}块中，你应该很高兴..
Something like below should work for you,
像下面这样的东西应该适合你，
var style = label.style;
try {
style.width = node.data.offsetWidth;
style.height = node.data.offsetHeight;
} catch (e) {
//do alternate when error
}
style.cursor = 'pointer';
style.color = '#fff';
style.fontSize = '0.8em';
style.textAlign= 'center';

You can use try...catch:
您可以使用 try...catch：
try{
allert('hello'); //Syntax error
}catch(err){
console.log(err);
}

If you know that your code is likely to encounter an error (for whatever reason) you can catch and handle the errors with a try/catch:
如果您知道您的代码可能会遇到错误（无论出于何种原因），您可以使用 try/catch 来捕获和处理错误：
try {
// Code that is likely to error
} catch(e) {
// Handle the error here
}
You can either do nothing with the error or try to recover your application. In this case you should probably try to find out why IE is throwing an error in the first place and see if you can avoid having to suppress the errors.
您可以对错误不采取任何措施，也可以尝试恢复您的应用程序。在这种情况下，您应该首先尝试找出 IE 抛出错误的原因，看看是否可以避免抑制错误。
