动态添加多个文本框的问题

Question

• 有两个内联的文本框，在它们旁边有一个“+”号。 单击加号后，会添加一个新的文本框，它将分别带有“+”和“ - ”号以便分别添加和删除文本框 。我使用this资源来实现我的文本框。 现在，我只想为每个文本框添加10个文本框。意思是10 用于关键​​字[]的文本框和用于link_name []的10个文本框，因为您可以在输入标签的名称中看到 。但是这个代码不起作用。

  如果我继续添加文本框为[]，然后19文本框 相加，然后，如果我尝试添加一个文本框LINK_NAME []那么它 不添加一个文本框，并显示关键字达到的最大限制。

  如果增加反之亦然，它可以正常工作。

• 另一个问题是反弹效应不起作用。没有太多 熟悉的影响，所以无法找到它不是 工作的原因。

jQuery和HTML如下所示：

jQuery的

$(document).ready(function() { 
    var id_1 = 2, max = 9, append_data; 
    /*TEXT BOXES FOR LINK NAMES*/ 
    /*If add_1 icon was clicked*/ 
    $("#add_1").live('click', function(){ 
     if($("div[id^='txt_']").length <9){ //Don't add new text box if limit is reached 
      $(this).remove(); //remove add icon from the current text box 
      var append_data = '<div id="txt_'+id_1+'" class="txt_div" style="display:none;"><div class="left"><input type="text" id="input_'+id_2+'" name="link_name[]"/></div><div class="right"><img src="add.png" id="add_1"/> <img src="remove.png" id="remove_1"/></div></div>'; 
      $("#textboxes_1").append(append_data); //append new text box in main div 
      $("#txt_"+id_1).effect("bounce", { times:3 }, 300); //display block appended text box with silde down 
      id_1++; 
     } 
     else{ 
      alert("Maximum 10 textboxes are allowed"); 
     } 
    }) 
    $("#remove_1").live('click',function(){ 
     var prev_obj = $(this).parents().eq(1).prev().attr('id'); //prev div id of this text_box 
     $(this).parents().eq(1).slideUp('medium', function() { $(this).remove(); //remove this text box with a slide up 
     if($("div[id^='txt_']").length >1){ 
      append_data = '<img src = "remove.png" id = "remove_1"/>'; 
     } 
     else{ 
      append_data = ''; 
     } 
     if($("#add_1").length< 1){ 
      $("#"+prev_obj+" .right").html('<img src = "add.png" id = "add_1"/>'+append_data); 
     } 
     }); 
    }) 

/*TEXT BOXES FOR KEYWORDS*/ 

    /*If add_2 icon was clicked*/ 
    var id_2 = 12, max = 19; 
    $("#add_2").live('click', function(){ 
     if($("div[id^='txt_']").length <19){ //Don't add new text box if limit is reached

      $("#txt_"+id_2).effect("bounce", { times:3 }, 300); //display block appended text box with silde down 
      id_2++; 
     } 
     else{ 
      alert("Maximum 10 textboxes are allowed"); 
     } 
    }) 
    $("#remove_2").live('click',function(){ 
     var prev_obj = $(this).parents().eq(1).prev().attr('id'); //prev div id of this text_box 
     $(this).parents().eq(1).slideUp('medium', function() { $(this).remove(); //remove this text box with a slide up 
     if($("div[id^='txt_']").length >1){

     } 
     else{ 
      append_data = ''; 
     } 
     if($("#add_2").length< 1){ 
      $("#"+prev_obj+" .right").html('<img src = "add.png" id = "add_2"/>'+append_data); 
     } 
     }); 
    }) 
});

好了，答案很简单，你已经做了一些逻辑错误，下面是你的代码，其中描述了一些修补程序n评论：

$(document).ready(function() { 
var id_1 = 2, max = 9, append_data; 
/*TEXT BOXES FOR LINK NAMES*/ 
/*If add_1 icon was clicked*/ 
$("#add_1").live('click', function(){ 
    if($("#textboxes_1 input").length <10){ //Don't add new text box if limit is reached 
// Here You have to check #textboxes_1 for his own input's, and You have to give 10 not 9, becouse lenght is allways actual number of elements 

     $(this).remove(); //remove add icon from the current text box 
     var append_data = '<div id="txt_'+id_1+'" class="txt_div"><div class="left"><input type="text" id="input_'+id_1+'" name="link_name[]"/></div><div class="right"><img src="add.png" id="add_1"/> <img src="remove.png" id="remove_1"/></div></div>'; 
// in the code abowe You give id="input_'+id_2+'", I belive it should be id="input_'+id_1+'" 
     $("#textboxes_1").append(append_data); //append new text box in main div 
     $("#txt_"+id_1).effect("bounce", { times:3 }, 300); //display block appended text box with silde down 
     id_1++; 
    } 
    else{ 
     alert("Maximum 10 textboxes are allowed"); 
    } 
}) 
$("#remove_1").live('click',function(){ 
    var prev_obj = $(this).parents().eq(1).prev().attr('id'); //prev div id of this text_box 
    $(this).parents().eq(1).slideUp('medium', function() { $(this).remove(); //remove this text box with a slide up 
    if($("div[id^='txt_']").length >1){ 
     append_data = '<img src = "remove.png" id = "remove_1"/>'; 
    } 
    else{ 
     append_data = ''; 
    } 
    if($("#add_1").length< 1){ 
     $("#"+prev_obj+" .right").html('<img src = "add.png" id = "add_1"/>'+append_data); 
    } 
    }); 
}) 

/*TEXT BOXES FOR KEYWORDS*/ 

/*If add_2 icon was clicked*/ 
var id_2 = 12, max = 19; 
$("#add_2").live('click', function(){ 
    if($("#textboxes_2 input").length <20){ //Don't add new text box if limit is reached 
// The same issue was here as well 

     $(this).remove(); //remove add icon from the current text box 
     var append_data = '<div id="txt_'+id_2+'" class="txt_div" ><div class="left"><input type="text" id="input_'+id_2+'" name="keyword[]"/></div><div class="right"><img src="add.png" id="add_2"/> <img src="remove.png" id="remove_2"/></div></div>'; 
     $("#textboxes_2").append(append_data); //append new text box in main div 
     $("#txt_"+id_2).effect("bounce", { times:3 }, 300); //display block appended text box with silde down 
     id_2++; 
    } 
    else{ 
     alert("Maximum 10 textboxes are allowed"); 
    } 
}) 
$("#remove_2").live('click',function(){ 
    var prev_obj = $(this).parents().eq(1).prev().attr('id'); //prev div id of this text_box 
    $(this).parents().eq(1).slideUp('medium', function() { $(this).remove(); //remove this text box with a slide up 
    if($("div[id^='txt_']").length >1){ 
     append_data = '<img src = "remove.png" id = "remove_2"/>'; 
    } 
    else{ 
     append_data = '';

    if($("#add_2").length< 1){ 
     $("#"+prev_obj+" .right").html('<img src = "add.png" id = "add_2"/>'+append_data); 
    }

})
