[英]callback json value by name/key
With this function I'm trying to get the licence name from a json url by name/key my json looks like this: 使用此功能,我试图通过名称/密钥从json URL获取许可证名称,我的json如下所示:
[{"Gallery":true,"Responsive":true,"Main":true,"Seasonal":true}]
js: js:
function getLicenseName(name, callback){
var license = 'default'
$.getJSON(adl+'DesignTemplateBuilder.aspx?GetLicense=1', function(data){
/*
licence = data[0].Gallery;
respValue = data[0].Responsive;
seasonalValue = data[0].Seasonal;
*/
licence = data[0].name;
callback(licence)
});
}
getLicenseName(name, function(Responsive) {
console.log(name);
//this returns empty right now
});
What I need is to get the true
or false
value using something like this 我需要的是获得
true
或false
方法是使用下面的值
getLicenceName(Gallery);
I need to use it in my functions eg: if(getLicenceName(Gallery)=false)...
我需要在我的函数中使用它,例如:
if(getLicenceName(Gallery)=false)...
function getLicenseName(callback){
$.getJSON(adl+'DesignTemplateBuilder.aspx?GetLicense=1', function(data){
callback(data)
});
}
getLicenseName(function(data) {
console.log(data[0].Gallery);
//this returns empty right now
});
Will do the trick. 会成功的。
You can't really do if(getLicenceName(Gallery) == false)
because the AJAX request is asynchronous, but you can do it this way: 您实际上不能执行
if(getLicenceName(Gallery) == false)
因为AJAX请求是异步的,但是您可以这样进行:
function getLicenseName(name, callback) {
$.getJSON(adl+'DesignTemplateBuilder.aspx?GetLicense=1', function(data){
// pass back the name parameter
callback(data[0][name])
});
}
// use quotes around the name
getLicenseName('Gallery', function (name) {
if (name) {
...
}
});
