HTML JavaScript接收参数的问题。

Question

Http://www.test.com/Photo_Success.aspx?params={nums:'" + num + "',category:'" + iAlbumId.ToString() + "'}&filenames=" + FileName   上面的这个URL如何获取params里的nums 和category的值。 谢了！

Answer 1

用javascript 接收到params这个参数的值，然后把值用Eval()转换成JSON就可以获取 nums 和category的值

下面函数是获取地址栏值

 

function getUrlParams() {
    var args = new Object();
    var query = location.search.substring(1);      // Get query string
    var pairs = query.split("&");                  // Break at ampersand
    for (var i = 0; i < pairs.length; i++) {
        var pos = pairs[i].indexOf('=');           // Look for "name=value"
        if (pos == -1) continue;                   // If not found, skip
        var argname = pairs[i].substring(0, pos); // Extract the name
        var value = pairs[i].substring(pos + 1);     // Extract the value
        value = decodeURIComponent(value);         // Decode it, if needed
        args[argname] = value;                     // Store as a property
    }
    return args;
}

 

var Params = getUrlParams()["params"];

var object_op = eval(Params);

var nums = object_op.object_op ;

var category =  object_op.category;
