获取页面跳转携带参数问题

function parseParams(param) {
    param = param.substr(1, param.length - 1);
    var paramArray = new Array();
    var pArray = param.split(‘&‘);
    for (var i = 0; i < pArray.length; i++) {
        var attributeArray = pArray[i].split(‘=‘);
        if (‘backUrl‘ == attributeArray[0]) {
            paramArray[attributeArray[0]] = pArray[i].substr(pArray[i].indexOf(‘=‘) + 1, pArray[i].length);
        }
        else {
            paramArray[attributeArray[0]] = attributeArray[1];
        }

    }
    return paramArray;
};

function openDetail(entCity) {
    $.ligerDialog.open({
        content: ‘<div id="wrapDiv"></div>‘,
        title: ‘检测详情‘,
        url: JWPT.projectName + ‘baseinfo/agrisample/agriSampleListForCount.jsp?entCity=‘ + entCity,
        height: 600,
        width: 800,
        isHidden: true,
        modal: true,
        isResize: true
    });
}

var param = window.location.search;
var paramArray = parseParams(param);
var entCity = decodeURI(paramArray.entCity);  //decodeURI函数解决传递中文参数乱码问题
