[英]JavaScript Array JSON.parse (string)
I am using eCharts (a JavaScript charting library) and there is something that's doing my head in. The examples use the following code for markLine (and it works as expected) 我正在使用eCharts(一个JavaScript图表库),正在做一些事情。这些示例对markLine使用以下代码(并且按预期工作)
markLine : {
symbol: 'none',
tooltip: {show: false},
itemStyle:{
normal:{
lineStyle:{
type: 'solid',
color: '#CCCCCC'
},
tooltip:{
show: false
}
}
},
data: [ [{ "xAxis" : 250, "yAxis" : 0 }, {"xAxis": 250, "yAxis" : 250 }] ]
}
I need to be able to get the data part as a JSON string, but I cannot get it to work. 我需要能够将数据部分作为JSON字符串获取,但是我无法使其正常工作。
Note: For simplicity, I have the same JSON information I receive as a string called arrayString : 注意:为简单起见,我具有与称为arrayString的字符串相同的JSON信息 :
markLine : {
symbol: 'none',
tooltip: {show: false},
itemStyle:{
normal:{
lineStyle:{
type: 'solid',
color: '#CCCCCC'
},
tooltip:{
show: false
}
}
},
data: (function (){
var res = [];
var arrayString = "";
arrayString = '[{ "xAxis" : 250, "yAxis" : 0 }, {"xAxis": 250, "yAxis" : 250 }]';
res = JSON.parse(arrayString);
return res;
})()
}
When I run the JSON.parse code the chart doesn't display, but if I console.log the value of 'res' the array appears to be created correctly. 当我运行JSON.parse代码时,图表不会显示,但是如果我console.log,则'res'的值似乎已正确创建。
Is anyone able to assist me with resolving this? 有谁能协助我解决这个问题?

您应该添加到res数组而不是忽略它吗?
res.push(JSON.parse(arrayString));
