学习驾驶员警报!
我正在尝试从下面的名为变量“name”的表单传输搜索字段内容，并将其输入到 flickr API JSON 请求标签字段(下面第 40 行)。我尝试了各种声明变量的方法，但似乎无法在网络上找到我要查找的内容。我猜是我不知道自己在寻找什么。
<!doctype html>
<html lang="en">

<style>
img {
height: 100px;
float: left;
}
</style>
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>

<body>
<form id="search">
<p><input id="search-name" type="text" placeholder="Type Region Here"></p>
<p><input id="search-submit" type="submit" value="Search For Region"></p>
</form>
<div id="images"></div>
<script>
var name;
$("#search").submit(function(event){
event.preventDefault();
var name = $("#search-name").val();
console.log("Search Term Was: "+name);
return false;
});
$("#search").submit(function(event) {
(function() {
var flickerAPI = "http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?";
$.getJSON( flickerAPI, {
tags: name,
tagmode: "any",
format: "json"
})
.done(function( data ) {
$.each( data.items, function( i, item ) {
$( "<img>" ).attr( "src", item.media.m ).appendTo( "#images" );
if ( i === 0 ) {
return false;
}
});
});
})();
});
</script>
</body>
</html>
有人愿意帮助/引导我走向正确的方向吗？
最佳答案
You do not need 2 event listeners for this.
var name = $("#search-name").val();will create local scope fornamehence you won't find value in globalname.
尝试这样:
$("#search").submit(function(event) {
event.preventDefault();
var name = $("#search-name").val();
var flickerAPI = "http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?";
$.getJSON(flickerAPI, {
tags: name,
tagmode: "any",
format: "json"
})
.done(function(data) {
$.each(data.items, function(i, item) {
$("<img>").attr("src", item.media.m).appendTo("#images");
if (i === 0) {
return false;
}
});
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
