使用jQuery读取本地json绑定表格

由于js安全不允许读写本地文件，采用引用脚本方式读取json

equation.js

1、读取并绑定表格

$("#btnOverview").click(function () {;
    var eHtml = ' ';
    for (var i = 0; i < edata.length; i++) {
        console.log(edata[i]);
        console.log(eHtml);
        if (i == 0)
            eHtml += '';
        else
            eHtml += '';

        eHtml += '' + edata[i].eid + ''
        eHtml += '' + edata[i].etype + ''
        eHtml += '' + edata[i].ename + ''
        eHtml += '' + edata[i].equation[0] + ''
        eHtml += '' + edata[i].desc + ''
        eHtml += ''
    }

    $("#indextbody").html(eHtml);
})

2、按类型查询

$("#btnSearch").click(function () {
    console.log("btnSearch");
    var searchType = $("#sType").val();
    console.log(searchType);

    var eHtml = ' ';
    for (var i = 0; i < edata.length; i++) {
        if (edata[i].etype == searchType) {
            for (var j = 0; j < edata[i].equation.length; j++) {
                if (i == 0)
                    eHtml += '';
                else
                    eHtml += '';
                eHtml += '' + edata[i].eid + ''
                eHtml += '' + edata[i].etype + ''
                eHtml += '' + edata[i].ename + ''

                eHtml += '' + edata[i].equation[j] + ''

                eHtml += '' + edata[i].desc + ''
                eHtml += ''
            }
        }

    }
    $("#lookuptable").html(eHtml);
})

3、录入新数据条目

$("#btnSave").click(function () {
    console.log("btnSearch");
    var saveType = $("#sType").val();
    var saveName = $("#sName").val();
    var saveEqua = $("#sEqua").val();
    var saveDesc = $("#sDesc").val();

    var saveJSON = {
        "eid": edata.length+1,
        "etype": saveType,
        "ename": saveName,
        "equation": saveEqua,
        "desc": saveDesc
    }

    edata.push(saveJSON);
    alert("微分公式插入完成");
})
