通过EL表达式,后台数据传到前台,引号及后面的数据被截断的问题:
如:
前端页面:
html:
问题解决:
1.一个简单的办法,把 input 写成这样:
<input type="text" name="data" value=' '>
value 值用单引号试试
2.更好的办法应该是做 HTML 转义,在数据传到前端前就要处理,用 java 里的相关函数:
mav.addObject("data", toHtml(form.getData()));
public static String toHtml(String s) { s = s.replace("&","&"); s = s.replace("<","<"); s = s.replace(">",">"); s = s.replace("\t"," "); s = s.replace("\r\n","\n"); s = s.replace("\n","<br>"); s = s.replace(" "," "); s = s.replace("'","'"); s = s.replace("\"","""); s = s.replace("\\","\"); return s; } //逆 public static String unHtml(String s){ s = s.replace("<br>","\n"); s = s.replace(" "," "); s = s.replace("<","<"); s = s.replace(">",">"); s = s.replace("&","&"); return s; }
3.js转义用 /
