Wrong presentation SyntaxError：Unexpected end of JSON input

 

  Solution

reason ： If the parameters of the object or the elements of the array are encountered, the address includes ?& - _ . ! ~ * ' ( ) When waiting for special symbols , object / The array must first pass JSON.stringify Convert to a string and pass through encodeURIComponent code , Reception time , Through the first decodeURIComponent Decode and pass JSON.parse Convert to JSON Formatted objects / Array .

Revised as follows ：

var selectWorker = JSON.stringify(selectWorker);
uni.navigateTo({
    url: '../recordForm/recordForm?selectWorker=' + encodeURIComponent(selectWorker)
})

onLoad(option) {
	console.log(option)
	var _this = this;

	//  Selected workers 
	var selectWorker = JSON.parse(decodeURIComponent(option.selectWorker));
	var workerIdsArray = [];
	for (var i = 0; i < selectWorker.length; i++) {
		workerIdsArray.push(selectWorker[i].id);
	}
	var workerIds = workerIdsArray.join(',');
	console.log(workerIds);
	_this.selectWorker = selectWorker;
	_this.workerIds = workerIds;
},
