如何将 URL 的结尾传递给 Value="";以一种形式 [英] How to pass the end of the URL to a Value="" in a form

问题描述

我的硬盘驱动器上有一个 .htlm 文件，它是我的书籍列表，顶部有一个表单和一个脚本，可以让我搜索文件的内容.我喜欢在浏览时访问这个文件.我使用带有扩展名Advanced URL Builder"的 Firefox，这个扩展允许我突出显示几个词，然后使用上下文菜单选择 Find with...\Google 或我编程的任何其他站点.其中之一是我自己的文件，这会打开搜索框上的光标焦点，但不会出现任何文本.

I have a .htlm file on my hard drive is a list of my books and at the top there is a form and a script that allows me to search the content of the file. I like to access this file while I am browsing. I use Firefox with the extension "Advanced URL Builder" this extension allows me to highlight a few words and then using the context menu select Find with...\Google or any other site I have programmed in. One of these is my own file, this opens the cursor focus on the search box but no text will appear.

打开页面时的 URL 如下所示:

The URL when I open the page looks like this:

file:///F:/MyBooks.htm?search_txt=War and Peace

? 之后的 search_text是我在Advanced URL Builder"中编写的程序= 符号后面的部分是上一个站点或页面中突出显示的文本

the search_text after the ? is what I have programmed in "Advanced URL Builder" the portion after the = sign is the highlighted text from the previous site or page

我正在使用从网站上获取的这个表单和脚本:

I am using this form and script that I picked up from a website:

<form name="search" action="file:///F:/MyBooks.htm" method="post"

onSubmit="if(this.t1.value!=null && this.t1.value!='')
findString(this.t1.value);return false">

<input type="text" name="t1" id="search_txt" size=100 value="" /> 
<input type="submit" value="Find" name=b1>
</form>

<script language="JavaScript">
<!--
var TRange=null

function findString (str) {
 if (parseInt(navigator.appVersion)<4) return;
 var strFound;
 if (window.find) {

  // CODE FOR BROWSERS THAT SUPPORT window.find

  strFound=self.find(str);
  if (strFound && self.getSelection && !self.getSelection().anchorNode) {
   strFound=self.find(str)
  }
  if (!strFound) {
   strFound=self.find(str,0,1)
   while (self.find(str,0,1)) continue
  }
 }
 else if (navigator.appName.indexOf("Microsoft")!=-1) {

  // EXPLORER-SPECIFIC CODE

  if (TRange!=null) {
   TRange.collapse(false)
   strFound=TRange.findText(str)
   if (strFound) TRange.select()
  }
  if (TRange==null || strFound==0) {
   TRange=self.document.body.createTextRange()
   strFound=TRange.findText(str)
   if (strFound) TRange.select()
  }
 }
 else if (navigator.appName=="Opera") {
  alert ("Opera browsers not supported, sorry...")
  return;
 }
 if (!strFound) alert ("String '"+str+"' not found!")
 return;
}
//-->
</script>

我需要的是能够将 URL 的最后一部分作为变量传递给表单的第 4 行

What I need is to be able to pass the last portion of the URL to the 4th line of the form as a variable

<input type="text" name="t1" id="search_txt" size=100 value="War and Peace" />

你能帮忙吗?

谢谢.

推荐答案

我通过修改上面的脚本仅 1 行就解决了 %20 的问题 - 感谢 Kaleb 和我使用他们部分代码的所有其他人完成工作.

I solved the problem of the %20 by modifying the above script only 1 line - My thanks to Kaleb and all the others that I used portion of their codes to get the job done.

<script>
function getParameterValue(name) {
    name = name.replace(/[\[]/,"\\\[").replace(/[\]]/,"\\\]");
    var regexS = "[\\?&]"+name+"=([^&#]*)";
    var regex = new RegExp( regexS );
    var results = regex.exec( unescape(window.location.href) );
    if( results == null )
        return "";
    else
        return results[1];
}

function setSearchText() {
        document.getElementById("search_text").value = getParameterValue("search_text");
}

var 结果 = regex.exec(unescape(window.location.href));通过将这一行更改为unes​​cape"，现在文本将进入搜索框而没有 %20.

var results = regex.exec( unescape(window.location.href) ); by changing this line with the word "unescape" now the text passes into the search box without the %20.
