Javascript 如何在CasperJS中设置带引号和双引号的选择器变量

我必须如何将此选择器变量设置为在CasperJS中工作（在Chrome控制台中工作）？

document.querySelectorAll('[data-product-unique-key="4_0_1"] [pf-aria-text="widgets.efgenericproduct.paymentaccount.Movements"]')[0]

以下是测试结果：

FAIL Find an element matching: ('[data-product-unique-key="4_0_1"] [pf-aria-text="widgets.efgenericproduct.paymentaccount.Movements"]')[0] 
#    type: assertExists 
#    file: /home//dev/casperjs/ccm/scenarios/global.js 
#    subject: false 
#    selector: "('[data-product-unique-key=\"4_0_1\"] [pf-aria-text=\"widgets.efgenericproduct.paymentaccount.Movements\"]')[0]"

这是我目前的代码：

// I escape the doublequotes using backslash
var btnMovements = "('[data-product-unique-key=\"4_0_1\"] [pf-aria-text=\"widgets.efgenericproduct.paymentaccount.Movements\"]')[0]"
casper.csvexport = function() {
    casper.thenOpen('https://www.foobank.com/ap/ba/fp/html/e-finance/assets', function() {
        });
    casper.waitForSelector(
        btnMovements,
        function success() {
            this.test.assertExists(btnMovements);
            this.click(btnMovements);
        },
        function fail() {
            this.test.assertExists(btnMovements);
        }
    );
};

您的选择器不正确：

var btnMovements = "('[data-product-unique-key=\"4_0_1\"] [pf-aria-text=\"widgets.efgenericproduct.paymentaccount.Movements\"]')[0]"

var btnMovements = '[data-product-unique-key="4_0_1"] [pf-aria-text="widgets.efgenericproduct.paymentaccount.Movements"]';

正确的选择器应为：

var btnMovements = "('[data-product-unique-key=\"4_0_1\"] [pf-aria-text=\"widgets.efgenericproduct.paymentaccount.Movements\"]')[0]"

var btnMovements = '[data-product-unique-key="4_0_1"] [pf-aria-text="widgets.efgenericproduct.paymentaccount.Movements"]';
