Question

您好我有一个ext js数据网格，用于排序和过滤已经正常工作，但用户发现了一个错误，我无法弄清楚它是什么？

其中一个itemID（产品）看起来像这样= 98694E130，但显示为986940000000000。

你能帮忙吗 - 让我知道我是否需要发布代码。

提前致谢

代码如下：

...

抱歉，如果格式化了

Answer 1

这是因为JavaScript将98694E130解释为98694*10^130。这被称为“科学记数法”。为了避免这种情况，请确保您的值是一个字符串，并且永远不会被非自愿地转换为整数（或任何数字类型）

从您的评论中看来，在您从服务器返回的JSON中，98694E130列的MATERIAL值未被引用，因此JavaScript会将其解释为数字。

Answer 2

如果你的函数的returnType是'struct'而你在函数上使用'returnFormat = JSON'属性，你可能想尝试这个：

将您的返回类型更改为“string”，将returnFormat更改为“plain”，然后将cfreturn更改为SerializeJSON（struckObj）

我发现这有时会解决这样的问题。
