更改URL中的参数值
我试图创建一个 javascript 函数来使用文本框中输入的值来更改 URL 中参数的值,但没有成功。那是因为我不是一名代码设计师,而是一名图表设计师。 这是我需要更改“城市”参数的 URL:
http://server/ad_new_customer.php?&city=&uri=http://server/adauga_exp.php
我正在通过使用 jQuery 的 MySQL 查询在输入文本框中生成数据,如下所示:
<input type='text' id='city' name='city' style="width:190px; align:left;" value="<?php echo $city; ?>" /> </td>
<script type="text/javascript">
//change the value of parameter in the URL function
function changeURI(key, value) {
var query = document.location.search.substring(1);
var query_q = query.split("?");
var vars = query_q[1].split("&");
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split("=");
if (pair[0] == key) {
vars[i] = pair[0] + "=" + value;
}
}
return vars.join("&");
}
//jQuery making the auto-suggestion query for the input ID
$().ready(function() {
$("#city").autocomplete("core/exp_city.php", {
width: 340,
matchContains: true,
selectFirst: false
}).return(changeURI("city", this.value}));
});
</script>
如何使其更改所选值上的参数值? 请各位设计师再次指教。 谢谢你!

我做了一个解决方法,用这个改变了changeURI()函数:
function changeURI(key, value)
{
key = escape(key); value = escape(value);
var kvp = document.location.search.substr(1).split('&');
var i=kvp.length; var x; while(i--)
{
x = kvp[i].split('=');
if (x[0]==key)
{
x[1] = value;
kvp[i] = x.join('=');
break;
}
}
if(i<0) {
kvp[kvp.length] = [key,value].join('=');
}else{
//this will reload the page, it's likely better to store this until finished
document.location.search = kvp.join('&');
}
}
在StackOverflow上找到并使用$.result()函数从jQuery查询中调用它:
<script type="text/javascript">
$().ready(function() {
$("#city").autocomplete("core/exp_city.php", {
width: 340,
matchContains: true,
selectFirst: false
}).result(function() {changeURI("city",this.value)});
});
</script>
I'm trying to make a javascript function to change the value of a parameter in the URL with the value inputed in a text box, with no luck. That's because I'm note a code designer but a graph one.
this is the URL where I need to change the "City" parameter:
http://server/ad_new_customer.php?&city=&uri=http://server/adauga_exp.php
I am generating data in the input text box through a MySQL query with jQuery like this:
<input type='text' id='city' name='city' style="width:190px; align:left;" value="<?php echo $city; ?>" /> </td>
<script type="text/javascript">
//change the value of parameter in the URL function
function changeURI(key, value) {
var query = document.location.search.substring(1);
var query_q = query.split("?");
var vars = query_q[1].split("&");
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split("=");
if (pair[0] == key) {
vars[i] = pair[0] + "=" + value;
}
}
return vars.join("&");
}
//jQuery making the auto-suggestion query for the input ID
$().ready(function() {
$("#city").autocomplete("core/exp_city.php", {
width: 340,
matchContains: true,
selectFirst: false
}).return(changeURI("city", this.value}));
});
</script>
How can I make it change the value the parameter on selected value?
Please advise, again, a humble designer.
Thank you!

I have made an workaround, changed the changeURI() function with this one:
function changeURI(key, value)
{
key = escape(key); value = escape(value);
var kvp = document.location.search.substr(1).split('&');
var i=kvp.length; var x; while(i--)
{
x = kvp[i].split('=');
if (x[0]==key)
{
x[1] = value;
kvp[i] = x.join('=');
break;
}
}
if(i<0) {
kvp[kvp.length] = [key,value].join('=');
}else{
//this will reload the page, it's likely better to store this until finished
document.location.search = kvp.join('&');
}
}
Found on StackOverflow and call it from the jQuery query with the $.result() function:
<script type="text/javascript">
$().ready(function() {
$("#city").autocomplete("core/exp_city.php", {
width: 340,
matchContains: true,
selectFirst: false
}).result(function() {changeURI("city",this.value)});
});
</script>

你遇到什么错误?你收到任何 JavaScript 错误吗?另外,尝试将代码更改为类似的内容
此外,问题中写入的 URL 在城市参数之前不应包含
&
,因为第一个参数以?
开头,因此URL 应该是:检查这是否是问题所在。
What error are you getting? are you getting any javascript error? Also, try changing your code to some thing like
Also, The URL written in the question should not have
&
before city parameter as the first parameter starts with a?
, so the URL should be :Check if that was the issue.
在您的示例中,
document.location.search.substring(1)
已经摆脱了问号:它应该返回&city=&uri=http://server/ adauga_exp.php
。然后对“?”进行拆分并尝试获取第二个数组元素应该返回未定义,因为不再有任何“?”人物。此时直接跳到 var vars = query.split("&") ,其余的对我来说看起来没问题。In your example,
document.location.search.substring(1)
is already getting rid of the question mark: it should return&city=&uri=http://server/adauga_exp.php
. Then doing a split on "?" and trying to take the second array element should return undefined, because there are no longer any "?" characters. Skip straight tovar vars = query.split("&")
at that point, and the rest looks okay to me.
