安装laravel后我们得到一个错误:
解析错误:语法错误,意外的T_CLASS,期望T_STRING或T_VARIABLE或第50行的C:\ xampp\htdocs\laravel\public\index.php中的'$'
我有一个json数组:
[
{"id":19,"name":"Jed", "lastname":"DIAZ", "hobby":"photo", "birthday":"2011/11/22"},
{"id":20,"name":"Judith", "lastname":"HENDERSON", "hobby":"pets", "birthday":"1974/06/12"},
{"id":21,"name":"Nicolai", "lastname":"GRAHAM", "hobby":"reading", "birthday":"2005/01/22"},
{"id":22,"name":"Vasile", "lastname":"BRYANT", "hobby":"singing", "birthday":"1987/03/17"}
]
用于从json数组中删除项目的函数
removeItem: function(removeId){
//paramater validation
return dataLoad.then(function(data){
f = data.findIndex(function(item) { return item.id == removeId; });
if(f < 0)
return false;
data.splice(f,1);
LS.setData(data,"cutomers");
return true;
});
}
代码运行时出现错误:
findIndex不是一个函数
错误行
f = data.findIndex(function(item) { return item.id == removeId; });
我是angular的新手,有一个管理一些客户数据的应用程序,它是一个存储在localStorage中的json文件,我如何在服务中创建部分更新补丁(delta)方法.
还需要一个错误处理.
JSON:
[
{"id":1,"name":"Gigi", "lastname":"DS", "hobby":"football", "age":"1987/06/04"},
{"id":2,"name":"John", "lastname":"Ciobanu", "hobby":"basball", "age":"2001/12/05"},
{"id":3,"name":"George", "lastname":"Doe", "hobby":"rugby", "age":"2003/05/09"},

HTML:

控制器:
.......
$scope.quickSave=function(c){
customerData.quickUpdate(c);
$scope.quickEdit = false; …我需要在 A4 纸上打印，每张纸都<div>从不同的页面开始
<div id="1">
//content
</div>
<div id="2">
//content
</div>
<div id="3">
//content
</div>
....例如，内容<div id="1">可能有 2 或 3 页，但<div id="2">仍需要从新页面开始。
