如何更改＆LT的名称字段;输入＆GT;在AJAX驱动页面？ [英] How to change the name field of an <input> in an AJAX-driven page?

问题描述

有关此目标页面（很抱歉，但等不允许超链接62.0.54.118）：

<$p$p><$c$c>http://62.0.54.118/search?&q=42&oq=42&sourceid=chrome&ie=UTF-8&filter=0

，我想换一个＆LT的名称字段;输入＆GT;默认使用userscript

输入为：

 ＆LT;输入类=gsfiID =LST-IBNAME =Q最大长度=2048值=42......＆GT;
 

我想将其更改为：

 ＆LT;输入类=gsfiID =LST-IBNAME =＆放大器; Q最大长度=2048值=42......＆GT;
 

也就是说，我想换个①到＆放，Q 在名称输入默认的领域。

我试着写一个脚本，（即不工作）：

  // == UserScript ==
// @name普通谷歌输入
// @include http://62.0.54.118/*
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js
// @require https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant GM_addStyle
// == / UserScript ==
/ *  - 的@grant指令需要解决设计变更
    通用汽车1.0推出。它恢复了沙箱。
* /
waitForKeyElements（输入[姓名* ='Q']，changeLinkQuery）;

功能changeLinkQuery（jNode）{
    VAR使用oldName = jNode.attr（'名'）;
    VAR了newName = oldName.replace（/ \ Q /＆放大器; Q）;

    jNode.attr（名称，了newName）;

    返回true;
}
 

此外，该页面是一个Ajax驱动的页面。​​

请修复我的坏脚本或帮我写一个又一个， 谢谢你。

更新： 我解决了其中的一部分，通过改变行我的脚本的来源：

  VAR了newName = oldName.replace（/ \ Q /＆放大器; Q）;
 

到

  VAR了newName = oldName.replace（/ Q /＆放大器; Q）;
 

然后我的脚本效果更好。感谢@Gerard塞克斯顿的提示。

但有一个新的错误，现在，与 waitForKeyElements 回调设置为返回true; 的页面的AJAX ，它添加了＆安培; 不停。

这导致该领域是 NAME =＆放大器;＆安培;＆安培;＆安培;＆安培;＆安培;＆安培;＆安培;＆安培; Q。等

我该如何解决这个问题？

解决方案

如果输入的名字只是①，其本身则仅仅是改变waitForKeyElements来电：

  waitForKeyElements（输入[名称='Q']，changeLinkQuery）;
 

这样它查找的完全的①，而不是AQ字符串中的任何位置。

如果这不是的完全的那名＆LT;输入＆GT; ，下面评论

For this target page (Sorry but SO doesn't allow hyperlinks to 62.0.54.118):

http://62.0.54.118/search?&q=42&oq=42&sourceid=chrome&ie=UTF-8&filter=0

, I want to change the name field of an <input> by default with a userscript.

The input is:

<input class="gsfi" id="lst-ib" name="q" maxlength="2048" value="42"...>

I want to change it to:

<input class="gsfi" id="lst-ib" name="&q" maxlength="2048" value="42"...>

That is, I Want to change the q into &q in the name field of the input by default.

I try to write a script, (that doesn't work):

// ==UserScript==
// @name     Normal Google Input
// @include  http://62.0.54.118/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js
// @require  https://gist.github.com/raw/2625891/waitForKeyElements.js
// @grant    GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change
    introduced in GM 1.0.   It restores the sandbox.
*/
waitForKeyElements ("input[name*='q']", changeLinkQuery);

function changeLinkQuery (jNode) {
    var oldName = jNode.attr ('name');
    var newName = oldName.replace (/\q/, "&q");

    jNode.attr ('name', newName);

    return true;
}

In addition, the page is an Ajax-driven page.

Please fix my bad script or help me to write another one, Thanks.

Update: I solved a part of that by changing a line of my script from:

var newName = oldName.replace (/\q/, "&q");

to

var newName = oldName.replace (/q/, "&q");

and then my script works better. Thanks to @Gerard Sexton for suggesting that.

But there is a new bug now, with the waitForKeyElements callback set to return true; for the page's AJAX, It adds the & non stop.

It causes this field to be name="&&&&&&&&&q", etc.

How can I fix it?

解决方案

If the input name is just q, by itself, then merely change the waitForKeyElements call to:

waitForKeyElements ("input[name='q']", changeLinkQuery);

So that it looks for exactly q, rather than a q anywhere in the string.

If that's not exactly the name of that <input>, comment below.
