Accessing query string/parameter from html page
html, query-string
Solution
This cannot be done in pure HTML.
This can be done in two ways, using JavaScript:
<body><script>
var param = /[&?]path=([^&]+)/.exec(location.search);
param = param ? param[1].replace(/"/g, '"') : '';
document.write('<object type="application/pdf" width="100%" height="100%">\n' +
'<param name="src" value="' + param + '" />\n</object>');
</script></body>
An alternative method is populating the parameter using DOM (demo: http://jsfiddle.net/N2GUf/2/):
<body><object type="application/pdf" width="100%" height="100%">
<param name="src" value="" id="param-path" />
</object>
<script>
var param = /[&?]path=([^&]+)/.exec(location.search);
if (param)
document.getElementById('param-path').value = param[1];
</script></body>
In either case, the query string is read from the `location.search` property, and parsed using a simple regular expression.
Problem
I have a basic html page which is having a query parameter being passed to the page. I thought I would be able to get the value with Request.QueryString but the more reading I'm doing seems that this is only for asp applications. My html is as follows below ``` <body> <object type="application/pdf" width="100%" height="100%"> <!--This didn't work--> <param name="src" value="<%=Request.QueryString["path"]%>" /> <!--Neither did this--> <!--<param name="src" value="<%=Request.Params["path"]%>" />--> <!--When it is hardcoded then my page is displaying the pdf as expected.--> <!--<param name="src" value="scan.pdf" />--> </object> </body> ``` I am calling the page with displayPdf.htm?path=scan.pdf I've been searching for a way to access query parameters in html without having to write a javascript solution but haven't had any luck. I'm sure adding a js function wouldn't be too big a deal just thought I would avoid it if there was a single line approach. Thanks for the help.
