Question

我有以下脚本。如您在运行代码段时所示，console.log无效。我该如何启用它？

datain = {
        "threshold": 1.5,
        "sample_response_score": 0.439,
        //"celltype_response_thres": 0.064,
        "celltype_response_thres": 'foo',
        "histograms": [
            {
                "sample": "Sample1",
                "nof_genes": 26,
                "values": [
                    {
                        "score": 0.042924727328924939,
                        "celltype": "Bcells"
                    },
                    {
                        "score": 0.073045907156188195,
                        "celltype": "DendriticCells"
                    }]
                  
                }]}
   
           



jQuery(function ($) {
     $.get(datain, function (data) {
         console.log(JSON.stringify(data));
       
       });
  });

Answer 1

console.log运行正常 - 你只是错误地使用.get，所以回调永远不会被触发。请参阅我的代码段。

请参阅jQuery.get的文档 - 期望获取数据的URL或具有url属性的配置对象。您似乎试图将它传递给您想要获取的结果对象。（感谢菲尔的纠正）

console.log('it works fine');
datain = {
        "threshold": 1.5,
        "sample_response_score": 0.439,
        //"celltype_response_thres": 0.064,
        "celltype_response_thres": 'foo',
        "histograms": [
            {
                "sample": "Sample1",
                "nof_genes": 26,
                "values": [
                    {
                        "score": 0.042924727328924939,
                        "celltype": "Bcells"
                    },
                    {
                        "score": 0.073045907156188195,
                        "celltype": "DendriticCells"
                    }]
                  
                }]}
   
           



jQuery(function ($) {
     $.get(datain, function (data) {
         console.log(JSON.stringify(data));
       
       });
  });

Answer 2

get：使用HTTP GET请求从服务器加载数据

示例：

$.get( "ajax/test.html", function( data ) { $( ".result" ).html( data ); alert( "Load was performed." ); });

＆＃13;
＆＃13;
datain = { "threshold": 1.5, "sample_response_score": 0.439, //"celltype_response_thres": 0.064, "celltype_response_thres": 'foo', "histograms": [ { "sample": "Sample1", "nof_genes": 26, "values": [ { "score": 0.042924727328924939, "celltype": "Bcells" }, { "score": 0.073045907156188195, "celltype": "DendriticCells" }] }]} //jQuery(function ($) { // $.get(datain, function (data) { console.log(JSON.stringify(datain)); // }); // });
＆＃13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
＆＃13;
＆＃13;
＆＃13;

也许您没有使用get正确加载来自服务器的数据。

您也可以使用ajax方法。

$.ajax({ url: url, data: data, success: success, dataType: dataType });

为什么我不能在Jquery中执行console.log
