Question

我正在尝试通过javascript创建一个用于过滤产品的查询。 SELECT * FROM TBN将在下一页。使用javascript jquery生成查询的其余部分

它将根据复选框勾选创建查询

    AND brand=Property 1 OR brand=Property 2 OR brand=Property 3
    AND price > Color 1 OR price > Color 2
    AND camera = Location 1 OR camera = Location 2

但是现在我需要添加一个“＃”; ＆＃39;像这样引用

AND brand='Property 1' OR brand='Property 2' OR brand='Property 3'
AND price > 'Color 1' OR price > 'Color 2'
AND camera = 'Location 1' OR camera = 'Location 2'

请某人帮助我。谢谢

Answer 1

将它与单引号连接起来

if (this.checked) byBrand.push("'"+$(this).attr("value")+"'")

Answer 2

您可以在代码中尝试此操作："'" + this.value + "'"

Answer 3

您只需在其值之前和之后放置单引号：

 $("input").on( "change", function() {
        var str = "";
        if (byBrand.length) str += "    AND brand='" +  byBrand.join(" OR brand='") + "'\n";
        if (byPrice.length) str += (str == "\n" ? "    ":"    AND price > '") + "" +  byPrice.join(" OR price > '") + "'\n";
        if (byCamera.length) str += (str == " \n" ? "    ":"    AND camera") + " ='" +  byCamera.join(" OR camera ='") + "'\n";

        $("#result").html(str);

    });

Answer 4

还有更多解决方案。

加入数组时添加引号：

(str == "\n" ? " ":" AND price > '") + "" + byPrice.join('\' OR price > \'') + "'\n";

使用引号存储值：
byCamera.push("'" + $(this).attr("value") + "'");

removeA(byCamera, "'" + $(this).attr("value") + "'");

Answer 5

试试这个

$("input[name=brand]").on( "change", function() {
    var v = $(this).attr("value");
    var v = '\''+v+'\''
    if (this.checked) byBrand.push(v);
    else removeA(byBrand, v);
});

Answer 6

var Products = [];
    $().ready(function () {
        Products.push({ ProductID: '1', ProductName: 'ABC', ProductCategory: 'XYZ' });
        Products.push({ ProductID: '2', ProductName: 'DEF', ProductCategory: 'XYZ' });
        Products.push({ ProductID: '3', ProductName: 'GHI', ProductCategory: 'XYZ' });

        alert('Product #: ' + Products[2].ProductID + '\n' + 'Product Name: ' + Products[2].ProductName + '\n' + 'Product Category: ' + Products[2].ProductCategory)
    });
