Conversion between a string json, json objects, an array of three

<script>
//json字符串、json对象、数组 三者之间的转换
        let jsonStr = '[{"id":"01","open":false,"pId":"0","name":"A部门"},{"id":"01","open":false,"pId":"0","name":"A部门"},{"id":"011","open":false,"pId":"01","name":"A部门"},{"id":"03","open":false,"pId":"0","name":"A部门"},{"id":"04","open":false,"pId":"0","name":"A部门"}, {"id":"05","open":false,"pId":"0","name":"A部门"}, {"id": "06", "open" : false, "pId": "0", "name": "A sector"}] json object is converted into a string json//json object is converted into a string json//json object is converted into a string json//   the let jsonStr1 the JSON.stringify = (jsonObj)json json string is converted into an object (original method)//var = jsonObj the JSON.parse (jsonStr)//json string into the object to json (method JQ)
        //= $ .parseJSON (jsonStr);
        the let jsonObj;'
     
        
        // the console.log (jsonStr1 + "jsonStr1") 

        // json json object into an array of objects into 
        the let of arr1 = [];
         for (the let I in jsonObj) {
             // var O = {};
             // O [I] = jsonObj [I]; 
            arr1.push (jsonObj [I]);             
        } 
        // the console.log (of arr1);
         // the console.log (typeof (ARR)); 
        var jsonStr11 = the JSON.stringify (of arr1) // JSON array into json string into
         // the console.log (jsonStr11); 
        var jsonArr = [];
         for ( var I in jsonObj){
                jsonArr[i] = jsonObj[i];
        }
        //console.log(jsonArr);
        //console.log(typeof(jsonArr))
</script>

 Object is converted into an array of a second embodiment

<Script>
 // the object into an array of 
    the let {obj = ' unfinished ' : 5 , ' Completed ' : 8 , ' to be confirmed ' : 4 , ' canceled ' : . 6 };
      var ARR = [];
     for (the let I in obj) {
         // arr.push (obj [I]); // properties
         // arr.push (obj [I]); // value 
        var O = {}; 
        O [I] = obj [ i]; 
        ARR. push (o);
    }

    function objToArray(array) {
        var arr = []; 
        for (var i in array) {
            var o={};
            o[i]=array[i];
            arr.push(o); 
        }
        console.log(arr);
        //return arr;
    }
   // console.log(arr)
    objToArray(obj);
</script>

 

About return and return false

1 can terminate the current execution method

2 will only return false to prevent submission of the form.

 

 

 

Find characters:

int index = item.LastIndexOf ( ' \ " ' ); // from the last position of the string began to find whether there is" the symbol
