Question

请考虑以下网址：

http://test/Preview.aspx?By=AJ_Swift&Title=Meeting_Planning_&_Participation

从上面的URL我将获取每个查询字符串值。对于Title查询字符串，我需要将其拆分为符号下划线'_'并用空格替换/ join。问题是“＆amp;”。 javasript分裂停在'＆amp;'并逃脱了一切。

var title = vars['Title'].split("_").join(" ");

给了我Meeting Planning

如何分割和加入，以便Meeting Planning & Participation

Answer 1

你可以简单replace _空格，如下所示。

"Meeting_Planning_&_Participation".replace(/_/g, " ");

整个代码：

function getParam(query, key) {
  var vars = query.split(/&(?![_])/);
  for (var i = 0; i < vars.length; i++) {
    var pair = vars[i].split("=");
    if (pair[0] == key) return pair[1];
  }
}

var url = "http://test/Preview.aspx?By=AJ_Swift&Title=Meeting_Planning_&_Participation";
var query = url.replace(/.*?\?/, "");
var title = getParam(query, "Title");
alert(title.replace(/_/g, " "));

Answer 2

function getQueryVariable(url, query) {

  url = url.replace(/.*?\?/, "");
  url = url.replace(/_&_/, "_%26_");

    var vars = url.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        if (decodeURIComponent(pair[0]) == query) {
            return decodeURIComponent(pair[1]);
        }
    }
    console.log('Query variable %s not found', variable);
}

用法：

var url = "http://test/Preview.aspx?By=AJ_Swift&Title=Meeting_Planning_&_Participation "
var By = getQueryVariable(url, 'By');
var Title = getQueryVariable(url, 'Title');
Title = Title.replace(/_/ig, " ");

console.log(By);
console.log(Title);

输出：

AJ_Swift
Meeting Planning & Participation
