无法绑定来自jQuery数据库中JSON值的下拉列表值

问题描述

我想根据来自database table的数据来绑定控制值。除下拉列表值未绑定外，所有控件（如文本框）都将绑定。

下面是我的代码

function BindDataTableToJSONProject(strVal) {

            var ProjectData = JSON.parse(strVal);

            var getJSONValue = ProjectData.Table[0];
            if (getJSONValue.PROJECT_MANAGER_NAME != "" && getJSONValue.PROJECT_MANAGER_NAME != null) {
                $('#ContentPlaceHolder1_ddlProjMan').val(getJSONValue.PROJECT_MANAGER_NAME);
            }
        }
    </script>

<select name="ctl00$ContentPlaceHolder1$ddlProjMan" id="ContentPlaceHolder1_ddlProjMan" class="form-control">
    <option value="0">--Select--</option>
    <option value="1">ABC</option>
    <option value="2">PQR</option>
    <option value="3">XYZ</option>
</select>

下面是我的json数据。

{ID: 6,MST_ID: 107,PROJECT_NO: "R4G-25-APD-210",CR_NO: "R4G-25-APD-ACR-1212",APPLICATION_NAME: "Workflow for VSAT Application",PROJECT_MANAGER_NAME: "XYZ", …}

解决方法

一种方法是循环遍历select标签内的bool Deck::isFull() { if (amountOfCards == 52) return true; return false; } ，然后检查Game::Game(Player& p1,Player& p2) { this->players[0] = p1; this->players[1] = p2; this->turn = 0; this->isGameOver = false; this->mainDeck = new Deck(); Card* C; //Initialize Deck for (int i = 0; i < 4; i++) { for (int j = 2; j < 11; j++) { C = new Card(j,Card::symbol(i),_T("Test")); this->mainDeck.addCard(*C); } Card *jack = new Card(11,_T("JACK")); this->mainDeck.addCard(*jack); Card* queen = new Card(12,_T("QUEEN")); this->mainDeck.addCard(*queen); Card* king = new Card(13,_T("KING")); this->mainDeck.addCard(*king); Card* ace = new Card(14,_T("ACE")); this->mainDeck.addCard(*ace); } } 是否等于class Deck:public Card { private: int amountOfCards; Card* deck; ，如果是，则向该选项添加options true。 / p>

演示代码 ：

.text()

PROJECT_MANAGER_NAME

,

您尝试设置值（即3）<option value="3">XYZ</option>

但是您选择文本getJSONValue.PROJECT_MANAGER_NAME == "XYZ"

的参数
