json作为ajax常用的一种数据类型,经常使用。但如果字段中出现换行符如何处理?
第一种解决方案:
后台代码把换行符\r\n替换为\\r\\n,前台代码js收到的字符就是\r\n,这时前端就可以根据\r\n做判断,替换为换行标签(br)
第二种方案:
后台代码对换行未做任何处理,直接给前端,这时前端就要这么处理了:
JSON.parse(JSON.stringify(s).replace(/\\n|\\r/g, "<br/>"))
<p v-html="regx(item.fieldOrignText)"></p>
第三种方案:
<pre>{{data}}</pre>
直接用pre标签展示内容,这时需要对比展示布局是否是需要的布局
仅供参考。。。。。。。

Adds pre-multiplication overflow detection to catch cases where dimension
products would exceed size_t max. The previous check only detected when
overflow resulted in exactly 0 or SIZE_MAX, missing other cases.
Retains the original post-multiplication check for backward compatibility.
Adds tests verifying overflow detection with dimensions (2^32+1)×(2^32),
which previously overflowed silently to 2^32.
This prevents custom SAX handlers from receiving incorrect array sizes
that could lead to buffer overflows.
