js 转换文本框的值(转)

本文介绍了一种使用JavaScript实现的文本转码方法,该方法能够将包含特殊字符和换行符的文本转换为HTML安全格式,非常适合用于处理从表单提交的数据。
今天做项目的时候遇到点问题 有一个大文本框,输入很多汉字 当然还要空格 分断
但是当我提交到数据库之后,查询出的结果很不令人满意,居然密密麻麻的一大片
无奈了,这时,白总给了我一个很好用的js代码,很好用,这里共享一下
function HTMLEncode(text){
   
    //text = text.replace(/&/g, "&") ;
    text = text.replace(/"/g, """) ;
    //text = text.replace(/</g, "&lt;") ;
    //text = text.replace(/>/g, "&gt;") ;
    text = text.replace(/'/g, "’") ;
    text = text.replace(/\ /g,"&nbsp;");
    text = text.replace(/\n/g,"<br/>");
    //text = text.replace(/\t/g,"&nbsp;&nbsp;&nbsp;&nbsp;");
    return text;
}
用法如下:
第一步
form表单
<form action="xx.jsp" method="post" id="formone">
  <textarea name="ttcont" id="ttcont" cols="50" rows="20">
  </textarea>

 <input type="button" onclick="subform" value="提交"/>
</form>
第二步
<script>
//转码的方法
function HTMLEncode(text){
     //text = text.replace(/&/g, "&amp;") ;
    text = text.replace(/"/g, "&quot;") ;
    //text = text.replace(/</g, "&lt;") ;
    //text = text.replace(/>/g, "&gt;") ;
    text = text.replace(/'/g, "’") ;
    text = text.replace(/\ /g,"&nbsp;");
    text = text.replace(/\n/g,"<br/>");
    //text = text.replace(/\t/g,"&nbsp;&nbsp;&nbsp;&nbsp;");
    return text;
}

//按钮调用的方法
function subform(){
//获取文本框值
var tempvar=document.getElementByIdx_x("ttcont").value;
//进行转码操作,然后重新赋值
document.getElementByIdx_x("ttcont").value=HTMLEncode(tempvar);
//提交
document.getElementByIdx_x("formone").submit();
}


</script>
根据下面的页面代码,需要编写这个js点击事件,点击明细表中每行的name为extendDataFormInfo.value(fd_3e59465a09231a.0.fd_3e5946689e29d2)的输入框,能跳到对应这个输入框的value里面的链接地址,页面代码如下:<tr> <td row="2" column="0,1,2,3" class="td_normal_title" colspan="4" style="width: auto;" width="undefined"> <script> $(function() { var tb = document.getElementById('TABLE_DL_fd_3e59465a09231a');
