最佳答案
我在 twitter 上使用 Typehead。我遇到了来自 Intellij 的警告。这导致每个链接的“ window.location.href”成为我的项目列表中的最后一个项目。
我如何修复我的代码?
下面是我的代码:
AutoSuggest.prototype.config = function () {
var me = this;
var comp, options;
var gotoUrl = "/{0}/{1}";
var imgurl = '<img src="/icon/{0}.gif"/>';
var target;
for (var i = 0; i < me.targets.length; i++) {
target = me.targets[i];
if ($("#" + target.inputId).length != 0) {
options = {
source: function (query, process) { // where to get the data
process(me.results);
},
// set max results to display
items: 10,
matcher: function (item) { // how to make sure the result select is correct/matching
// we check the query against the ticker then the company name
comp = me.map[item];
var symbol = comp.s.toLowerCase();
return (this.query.trim().toLowerCase() == symbol.substring(0, 1) ||
comp.c.toLowerCase().indexOf(this.query.trim().toLowerCase()) != -1);
},
highlighter: function (item) { // how to show the data
comp = me.map[item];
if (typeof comp === 'undefined') {
return "<span>No Match Found.</span>";
}
if (comp.t == 0) {
imgurl = comp.v;
} else if (comp.t == -1) {
imgurl = me.format(imgurl, "empty");
} else {
imgurl = me.format(imgurl, comp.t);
}
return "\n<span id='compVenue'>" + imgurl + "</span>" +
"\n<span id='compSymbol'><b>" + comp.s + "</b></span>" +
"\n<span id='compName'>" + comp.c + "</span>";
},
sorter: function (items) { // sort our results
if (items.length == 0) {
items.push(Object());
}
return items;
},
// the problem starts here when i start using target inside the functions
updater: function (item) { // what to do when item is selected
comp = me.map[item];
if (typeof comp === 'undefined') {
return this.query;
}
window.location.href = me.format(gotoUrl, comp.s, target.destination);
return item;
}
};
$("#" + target.inputId).typeahead(options);
// lastly, set up the functions for the buttons
$("#" + target.buttonId).click(function () {
window.location.href = me.format(gotoUrl, $("#" + target.inputId).val(), target.destination);
});
}
}
};
在@cdhowie 的帮助下,更多的代码: 我将更新更新程序,也为点击() href
updater: (function (inner_target) { // what to do when item is selected
return function (item) {
comp = me.map[item];
if (typeof comp === 'undefined') {
return this.query;
}
window.location.href = me.format(gotoUrl, comp.s, inner_target.destination);
return item;
}}(target))};
